Надо написать рассказ на о случае из жизни

The day was sunny. I and my little brother were walking around the city. My brother and I went to almost all the sites in our area. I wanted to drink. I left my brother at the entrance to the store and went to buy water. A few minutes later I came back, but somewhere has got a brother. After a half hour of searching, I found it  with my angry mother. This evening I will never forget, it was painful!
