I am a student now. I am always teased by my classmates and not respected by others. I want to avoid this problem in high school. What should I do?

This problem is more complicated. From the perspective of gaining the respect of classmates, we should first respect classmates, including their living habits and views on study or life. Especially if you don't do anything that disrespects your classmates, even if you communicate with each other, you should use polite language, including body language. For example, if a classmate greets you and you are busy, it is really difficult to answer directly. You must nod or blink. You'd better not have this habit of joking between classmates, because it is common to joke too much, so you don't joke with every classmate. You solemnly show your attitude to every classmate who wants to joke with you in an appropriate environment: you don't want to joke, you don't joke with every classmate, and I hope that classmates don't joke with you. This is feasible for most students, but not for a strong and aggressive individual, so you should treat him silently and ignore him. The most important thing is that you should study hard. As long as you get good grades and do something useful for everyone in the class, everyone will agree with you and respect you.
