I don't think anyone has "the right to be rude" towards anyone, and not Manny either. It was their relationship and this is all over and done with. They both handled it poorly in my opinion, and his friend's outlash was completely uncalled for, but that doesn't justify being an ass towards the man. And honestly, we will never know half of what went on between them. I'm sorry, but I think you're absolutely wrong in thinking you have the right to be a jerk. They're both adults who don't need people they don't know pop up in their face and start inquiring.
