Recently, three owls appeared suddenly on our campus. They made me think of my pet from childhood. When I was little, we had an owl at home. It was small, gray, and had two big eyes. We liked it very much. Every time I went home, it greeted me by making "goo-goo" sounds. We always played with it and talked to it. It would blink its eyes just like it understood what we were saying. It was like my best friend. But when the weather became colder, we forgot to keep it warm, and it died. It made us sad for a long time, and it also taught me how important it is to take care of animals.
