I have been laughed at since I was a child. I am a fool, or I will be bullied. Please help me tell me what I should do.

There must be something wrong with your words and deeds. At first glance, it is stupid or bullying. If you do something that others find unpleasant, you will find fault with you. Reading more news and entertainment magazines can bring you knowledge and topics to talk with people around you, so that you can mingle with them and won't feel stupid. Also pay attention to your dress, don't be too old-fashioned, and take the normal route. A person looks energetic, speaks flexibly and behaves generously. Who will oppose you for no reason? Say what you have to say, and don't talk nonsense if you can't. You would rather laugh, and honest people will not be bullied often.
