I once met such a good friend. When you tell him your secret, he will spread it to many people for you. The point is that he doesn't think it's wrong. What's more, he will laugh at you with others, give you nicknames and make fun of you every day.
Don't mention how tired such a friend is. He is indifferent. You regard him as a good friend, but you are dispensable to him, which is completely unimportant.
Mainly when you decide to leave him, he will unite with other students, stand on the moral high ground and condemn you, reveal all your secrets and embarrass you frequently, but you can't do anything about him. This is very tiring.
So it is such a friend that makes me very tired, and I believe everyone will be very tired. I hope you can meet good friends and don't meet such people.
The above are my views and opinions, I hope to help you!
