Aesop's fables are really interesting, and the more you read them, the more exciting they become. There is a story called "Sick Deer" that deeply educated me. This is about a sick road, because some fair-weather friends came to visit his home and finally ate all his food. Later, because there was nothing to eat, the deer starved to death. I was shocked to read this story, because I have many friends, but many of them are greedy and unprofessional. My mother often tells me to break up with them, but I don't listen. Now this story makes me very worried about myself. Will I end up like this one day? For my own tomorrow, I decided not to associate with those people. I have made some good friends with good moral character. As a result, my grades got better and I became morally upright in my studies. This makes me very lucky, and it also makes me realize that to make friends, I must make some capable, harmless and good-natured people, and it is good for me to make fewer useless people as friends.
