Password

I managed to forget my password for facebook earlier this week.  I don't even know how that's possible.  I type it at least once every day for the past 4-5 years...  I ended up changing my password but then the next day I realized that I was being dumb and typing an additional number to my actual password.  I'm too lazy to change it back to what it was originally and the old one was a less secure password anyways, no it wasn't password or 123abc.
