I was "forced" to make an account by my mom at some point, so I did. I set the profile picture to something completely random and promptly logged out. The only time I've logged in since then was to accept my wife's friend request (or whatever they call them) after we'd been married for over a year, since apparently her friends were confused why we weren't labelled as "in a relationship" or whatever.

Look, we're married. I don't need Facebook to tell you that. >_>
