Um...
Well, for a few days, I'll probably be one of a many people asking why it got shut down, try to get it back up, try to compromise and make sense of the situation, and everything of the like.
After that, I'd typically get over it by actually getting my life back since I've been going on and on from forum to forum growing addicted to a particular one. With PC gone, being the only forum I go to anymore, I'd actually be able to go outside without wanting to stay on here and feed my addiction.
So yeah, I'd go back to hanging out with my friends, with the occasional use of the computer and the internet apart from designing, which would probably be hard since I plan to focus a career the fundamentally uses computers over everything.
