I 15 years old, with a waist circumference of 87 cm. I like swimming, but I'm afraid my classmates will laugh at me. If you were my classmate, what would you think? Please give me some advice.

A child who is only eight or nine years old walks up to a little girl who is similar to him and says, close your eyes and I'll give you a good one. Just when the little girl was looking forward to it and I envied being single, the little boy lit a firecracker next to the little girl. From the sad cry of the little girl, I realized the coldness of this world. . .
