There are friends, and there are friends.
As it turns out, I have friends who are willing to help me break into my own house because I forgot my keys and apparently the spare keys have been given to a guest so that she can get in and out (and had since left the house), and our house is apparently immune to all known attempts to defeat it's security using a credit card. I feel that I am a lucky man on this account.
For this, I would like to graciously thank
neko_jin and Chris for taking half an hour out of their schedules to help me get back into my own house...
