Nothing too crazy, I guess. And if they start being too demanding, they're out.

Once, I had to pull the hair of my best friend back while she was throwing up because we had gotten drunk with too much vodka while filming ourselves and eating tons of weird cakes.
I remembered she was rude to me and it made me angry.
As if she wasn't appreciating the fact that I was trying to help her...
I also hit someone because he was being disrepectful to my friend.
I think you should confront your friends before they start to get used to come to you for any problems they might have. It's not an healthy situation. And you wouldn't have posted this thread if you weren't fed up with their demands.
