My Experience in Ghana

    I decided to take part in an exchange program in Ghana. The 30 of us participating in the program met up the first morning in Ghana to meet Fred, our guide in Ghana.

    We boarded the bus to Senase, a village of 3,000 in Northwest Ghana. Once we got to the village, we were greeted by the queen mother and the other elders. A young girl performed a dance for us with Ghanaian drums, and then the elders each thanked us for coming to the village and helping their children and their schools.

    After our meeting ended, we split up into three groups and went to different schools, spending most of the day handing out toothbrushes and school supplies, meeting with the children, and playing games with various classes. It was really interesting to see the schools and to see what all of the different classes were learning.

    We got back to our host's house that night literally seconds before the skies opened up over Senase, and since the power was out, Fred, Cari (my roommate) and I sat out under the roof listening to the pouring rain and talking about our lives. We were able to hear Fred's story, which was absolutely incredible. I can say it gave me a new sense of respect for the Ghanaian people, their unity in the face of tremendous hardship, and the immense amount of care and love they hold in their hearts, not only for their families but their entire community.

    The next day we performed our dance for one of the schools, to the delight (and laughter) of the children, queen mother, and principal. After that we were on the bus heading back.

    During the bus ride, new thoughts and questions filled my mind. Where is this fire Senase lit in my heart going to take me, and how can I feed it and build it into real change? How do I bring this back to my community, and then back home to my family and friends? These were only a few of the questions that I was struggling with and continue to struggle with, and I can't say I have found any answers yet. All I know is that Senase did light a fire within me, and I refuse to ever let it burn out.

    My first week in the United States was a cultural shock. Everything felt new to me, including the style of conversation, the community I lived in and even the type of food people ate.

    In our community back home, people eat mutton and chicken. Pork and beef are also common among other communities, but eating beef is taken as an illegal act. Unlike Nepal, eating beef is common in the West where most of the people follow religions other than Hinduism.

    Food is just an example. When people move from one part of the world to another, they should adapt（适应）themselves to the new culture. For example, going to the bars or getting drunk is not acceptable in my community, but it is common in the US after a certain age.

    I was raised in a traditional Hindu family in Nepal. We have a conservative（保守的，谨慎的）opinion towards marriage. Arranged marriages（包办婚姻）are common in which families decide whether the two should get married. Free love marriages are not allowed and are seldom seen. Same-sex marriage is also considered impossible.

    To me, culture is a matter of habit. The culture is so deep-rooted in people's minds that most people are against changes. It is always easy for them to do what they have been doing throughout their life. It may be difficult for anyone to adapt to a new culture.

    However, with travel being an unavoidable thing for modern people, one always comes across different cultures. In such cases, one should be respectful and adaptive to the culture other people follow. The world is always a better place to live in when we have spaces for people of all cultures.

    One February afternoon, Jesus Delgado was on break behind T2 Tacos, where he works as a cook, when he heard a commotion(骚动). He ran to the front of the Los Angeles Taco stand and saw a man and a woman arguing. She was screaming for help and had two young boys at her side. All of a sudden, the man hit her in the mouth, seized the smaller boy, and ran down the street.

    "I followed my judgement and chased him." Jesus, 35, told the Argonaut newspaper. The older boy ran in the other direction to get help. A group of teenagers who had witnessed the attack assisted the woman, Lauren Kornacki, and called 911. She told them that she was the boys' babysitter.

    Within a few blocks, Jesus caught up to the man, Andron Gazarov, 33. They fought, and Jesus wrestled (抢夺) the young boy from Gazarov's arms. Then Gazarov threw himself onto the sidewalk. "He was yelling at me that the kid didn't belong to me. I was telling him the kid didn't belong to him," Jesus told the Argonaut.

    Minutes later, Los Angeles police officers arrived and arrested Gazarov, who was charged with kidnapping, attempted kidnapping, and attack. He faces up to 12 years in prison, if convicted (定罪). The kids, Brendan O'Brien, 6, and Grady O' Brien, 4, were unharmed.

    The next night, the boys' father, Tom O'Brien, went to the Taco stand to thank Jesus for his actions. He also started an online fund to help Jesus pay the medical expenses for his special-needs daughter. By May, more than $27,000 had been raised.

    Spending money on time-saving services reduces stress and boosts(增进）happiness according to a new research, but shockingly, few of us do it.

    Whillans, a professor at HBS said, "Buying time helps to protect us from the stress in our lives caused by time pressure, and the feeling that we don't have enough minutes in the day to complete our tasks."

    The effect was clearest in the Canadian experiment, in which 60 working adults were given $40 to spend in two different ways. One weekend, they were told to spend the money on a material purchase—a gift for themselves. The next weekend, they were instructed to spend the $40 on anything that saved them time,  from paying the neighbor ' s kid to run errands (跑腿）to taking an Uber instead of a bus.

    "On the day they made the time-saving purchase, they felt happier, in a better mood, and lower feelings of time stress than on the day they bought a material purchase, " said Whillans.

    The biggest surprise to the researchers was how few people would spend money on time-saving services. When they asked 98 working adults how they would spend a "windfall"(意外之财) of $40, only two percent named a purchase that would save them time.

    "One reason," said Whillans, "is that we're very bad at remembering how much we hate doing certain tasks once the suffering has passed. That makes us less likely to take active steps to avoid that overburdened feeling in the future. "But another possible cause is good old-fashioned guilt." If you feel guilty about getting someone to clean your house for you, then you might get less happiness from outsourcing (外包）that task, " said Whillans, "or you might just be less likely to spend your money in that way."

    Wolves are important animals in the traditions and stories of most Native American tribes. To Native Americans, wolves often represent bravery. The animals also are signs of strength, loyalty, and success at hunting. Other cultures--such as the ancient Celtic and Nordic peoples-also placed high value on wolves.

    However, from the wolves in horror films to the wolves in children's stories, wolves get a bum rap(不公正的惩罚) in both literature and English expressions.

    To begin with, there is the term lone wolf. The lone wolf isn't a bad person. But they like to do things on their own. However, the term can mean something less than desirable. Lone wolf makes you think the person doesn't want to be around people because he or she dislikes them.

    Now, let's move on to the home.

    Parents might criticize their children for wolfing down their food. In other words, the child eats very quickly and without care. And if someone says a child was raised by wolves, that child has bad manners and is behaving like a wild animal. A wolf at the door means someone to whom you owe money is waiting just outside your door.

By the way, there are two popular wolf-related expressions that come from Aesop, the ancient Greek storyteller.

    The first is a wolf in sheep's clothing. A wolf in sheep's clothing describes someone who acts and looks nice on the outside but is bad on the inside.

    Aesop's other wolf fable also involves a shepherd, but not a hardworking one. He is known as the boy who cried wolf. People who cry wolf are not trusted. People are so familiar with this story, you simply have to say cry wolf for them to know what you mean.
