So I am currently a college student, and we had a three day weekend. A couple of friends and I decided to head to one of their houses so that way we could go see a hockey game. One of my friends is roommates with one of my really good friends, and he was complaining about living with him. The complaints slowly turned into them just ripping into the man, and were just downright hurtful. Sadly, I participated in some of the comments and didn't make any attempt to stop them. Finally fed up with all of the comments, I told my friend what they said about him and told him what I said also. I then proceeded to call those two friends out, and they are now not talking to me anymore. They also told me to grow up. Did I do the right thing or wrong thing? AITA?
