As an April fool's joke, I'm going to use my friend's face as a profile picture.
For what reason would you use your friend's face?
He deserves it for being so mean to me.
I understand they were being mean but getting back at people is wrong to do. They will be upset and find a way to get back at you then it never ends.
I think that you are clueless.
Getting back at your friend is wrong and isn't going to correct their behavior moving forward. It sounds as the two of you don't care for each other much and it might be best for you both to part ways as friends. Some friendships aren't meant to last forever and this one seems to have delved into unhealthy territory.
