I still remembered one thing. One day last month, Cindy got a stomachache, so I took her to see a doctor. When we waited in line outside the waiting room, we saw a lady beside us. She looked very upset. Then Cindy gave a smile card to the lady, saying," I hope everything goes well." The lady hugged Cindy and said nothing. Later, Cindy gave out five more smile cards that day.
Last Monday, I went shopping with Cindy in a supermarket. After shopping, we went to the cash register (收银台). To my surprise, I couldn't find my wallet and I didn't know what to do. At that time, a lady came to us and paid for the bill for us. She was just the lady who was at the doctor's that day. I said" thank you" to her. She said,"I was moved by your daughter's kindness." Then I returned the money to her the next day.
Now our family members always enjoy helping others. It makes us happy. And giving out smile cards is a good way to help others.
