On Saturday morning, my mother and I went shopping in the supermarket, and soon we returned home with a full load. On the way home, an old lady walked in front of us with something in her hand. I thought to myself, "Grandma has a lot of things in her hand. How can she open the door?" I hurriedly asked my mother for a key card and ran to find my grandmother. As he ran, he said to his grandmother, "I'll open the door for you." Grandma smiled and said to me, "What a sensible child, thank you." I replied politely, "Grandma, you're welcome." After grandma left, I stood at the door waiting for my mother, feeling flattered.

It turns out that helping others will also make you happy. So I will do more good deeds and try to be a good example to help others.
