I've done it. I always said I wouldn't, but I have. I've created a Facebook account.
It's a lot like when I got contacts. I was talking it over with my brother's girlfriend and she said, "Wasn't it just last week that you said you'd never get contacts? That your glasses are such a part of who you are that you can't imagine not having them? Wasn't that last week? Yeah, I think it was."
But then the desire for sunglasses became too strong and I got contacts.
Anyways, poke me or something.
