Why is my friend mad at me?

[Josh]

Ok so I'm in class for lunch and my friend is too. So I was a little depressed and I put alot of depressing stuff on twitter so he must of been on too and he came over and leaned on my shoulder and asked was I ok, I said yeah thanks and he said no problem then I did his usual rapping and singing thing when he listens to must so i rapped something to me about him being real so I put on twitter that he is so fake but It was a joke and then instantly HE PUTS ME ON BLAST AND LIKE CUSES ME OUT AND SAID DONT CALL ME "BRO" ANYMORE!! ALSO HE UNFOLLOWED ME and DIDNT talk to me the rest of the day...two things. 1. Did I do anything wrong and 2. How do I get my bro/friend back???
