My roommate has a friend in town. They'd gotten up around noon and been gone all day. I went for a run around 6:30. Normally, if I go running and she's not home, I take both the doorknob key (it locks automatically) and the deadbolt key for just in case she'd come home, leave again, and lock the deadbolt. This time, I thought, "I'm only running three miles. What are the chances that they'd come home in the next half hour and leave again?"
Turns out, the chance of that happening was 100%.
On the upside, I met my neighbors across the hall and they are very nice and helpful people. Seeing as how I don't know my roommate's number, they allowed me to use both their computer to find it in my email and their phone to call her. You know how sometimes you get a call and you don't know the number so you don't answer it? You should really answer it. It might be your roommate calling from the neighbor's phone.
So they also let me use their phone to call Raj (whose number I actually do know, on the principle that I ought to know one person's phone number in the city where I live) to ask him to come and pick me up. I'd been home from running for an hour and a half by then and was sweaty and freezing. Naturally, about fifteen minutes after Raj arrived and started driving me to his house, Megan called him, having gotten the number off my phone, conveniently located on my bed.
All of this happened just after I'd congratulated myself on not being a crazy person since I only checked one time (as opposed to my usual 3-8 times) to make sure that my doorknob key and door access card were in my shoe pouch. And I'd denied the crazy impulse to leave a note saying that I was out running and if they should come in and leave, please don't lock the deadbolt. Or to just take the one extra key for just in case.
Great. Now that Inner Crazy Girl was right about something, the chance that I'll get her to shut up again hovers right around 0%.
