Write a composition about how to find a mother when a child gets lost in the park.

One day, my mother and I went shopping in the park. In the goldfish shop that just entered the door, I saw a little brother crying and looking around anxiously. I couldn't help going over and asking him why he was crying. It turned out that he was separated from his mother. So I consulted my mother and finally decided to go to the service desk to broadcast. At the reception desk, the waiter also enthusiastically helped the little brother broadcast to find his mother. At this time, my mother and I were about to leave the service desk. I looked back and saw my little brother looking nervous and scared, so I asked to stay with my little brother and wait for my mother.

Next, I tried to amuse my little brother, including playing games with him and telling him stories. My little brother was teased. After a while, an aunt rushed over. When my little brother saw his mother coming, he rushed over and hugged her tightly. ...

Seeing this moment, my heart is sweeter than eating sugar, and I realize that helping others will make me feel happy.
