I'm mad at my friend for being mad about her friend.
Why are feeling so much anger towards your friends?
I'm mad at one for calling my friend ugly.
I suggest you to talk to your friend to hear the full story. I think that you should hold off on getting upset until you know what has actually happened.
Fuck off, I'm angry and I don't care.
Of course you care. Why would you bring it up if it doesn't made anything to you. Calm down a bit and just talk to your friend. There is no point in getting angry at something that maybe didn't even happened.
