I really want to answer this but.. I have become comfortably numb.
Personally I couldn't care less about people who 'attack' me on the forums. And people that are rude to me without cause are doing me a favor, because I'm instantly aware that they're the kind of person I don't want anything to do with.
Too many people subscribe to "Hey, I'm anonymous here, yay I get to be an asshole LOLOLOL" magazine. Its a shame, but those people aren't worth giving a shit about.
If anything they just make the decent, helpful people that much more awesome.
Appreciate your time with friends and family while they're here. Don't wait until they're gone to tell them what they mean to you.
