GlaDos: There was even going to be a party for you. A big party, that all of your friends were invited to. I invited your best friend, 'the Companion Cube'. Of course, he couldn't come, because you murdered him. All your other friends couldn't come either, because you don't have any other friends because of how unlikable you are. It says so right here in your personnel file; 'Unlikable. Liked by no one. A bitter unlikable loner whose passing shall not be mourned.' SHALL NOT BE MOURNED. That's exactly what it says. Very formal. Very official. It also says you were adopted. So that's funny too.
"Few people are capable of expressing with equanimity opinions which differ from the prejudices of their social environment. Most people are even incapable of forming such opinions." - Albert Einstein
