That some of you would consider a person we've always known so little of a true friend speaks only to your exceedingly low standards. And to continue to like him after the revelation that in fact, yes, he was a total liar all long means you just have none.
I have heard most of the 'sock' rumours about people, and maybe I'm not in the loop... but I never thought he was a sock, let alone one of 'his'.
So, he kind of made fools out of a lot of us. He wasn't a friend, he was a fraud. And if you're happy being friends with a persona, that's your call but you might need to re-evaluate some of your choices.
