An unforgettable thing is that when I was a child, my parents asked me to help others, and I have always been willing to help people in need, but the most unforgettable thing happened that day. One day I came home from school and saw an old woman on the side of the road. I asked my grandmother, "Why don't you cross the street?" Grandma said, "I can't walk easily and my eyes can't see clearly." Grandma said, "Can you take me there?" I readily agreed. My right hand is holding grandma's left hand, and we will start walking when the green light is on. When the green light was on, I walked on grandma's left and slowly led her on the sidewalk. The green light stopped, and grandma and I walked to the other side of the sidewalk. Grandma said to me, "You are a good boy!" My heart was sweeter than honey at that time! I asked my grandmother, "Where do you live?" Grandma said, "It's just ahead." So I said to my grandmother, "Let me take you home!" Grandma walked beside me and I told her a joke. Grandma smiled happily after hearing my joke. So I sent my grandmother home, and I was very happy. This is my most unforgettable thing, because it lets me know that you have helped others and made yourself happy.
