My friend tells me to shut up a lot. How do I do that? They say they're starting to hate me.

Consider when your friend is saying this to you. If it's during class, then perhaps heed the advice because your friend is trying to listen to the lesson. On the other hand, if it's during lunch or other times when socializing, it's possible your friend is being rude and controlling and isn't such a great friend. If you do talk too much, about things that people find boring, learn to recognize when you're doing this and change the subject or let someone else talk for a while. In class, be a little quieter but not so quiet that you don't answer or ask questions. And if you are saying interesting things often but your friend is being mean, then reconsider the friendship.
