I'm trying to help my best mate who can't even look at me and goes straight to the bottle instead of to me when someone comes through and reminds him that he was accused of being a traitor, a Death Eater, and spent years rotting in jail for murders he didn't commit. So have some respect for that. I don't give a fuck that I haven't "lived" through it because I die. I'm dead, Harry, so I can't try to help him through that. I can't help him, I can't help Remus, and I can't help you. If I have to ask people to back off when people come in around that time and calling Sirius a traitor and all that, then I'll do it.
And if you can't see that I'm trying to help and start lecturing me on things I don't know when I stated numerous times above that I've talked to people to learn the truth, then that makes you an arse too.
