It is (自然的) for parents to worry about their children when they are away on. (出差). They are afraid their children can't take care of (他们自己) . But in my (观点) , I don't think they need to do that, because we are not little children any more. And it is very (方便的) to ask for help on We chat. I remember last time when my parents went (国外) for a one-week meeting. My parents talked with me on We chat every night. With the help of them, I (管理) my own life well and learned to do lots of house work. I finished my homework on time. I even cooked meals myself (代替) of eating fast food. When I cooked for the first time, I was so worried that I kept asking my parents for help. I was happy the food was not (烧糊) at last. The experience of staying home alone made me even more (自信的) and independent.
