Our roomba fell down the stairs last night. It was pretty epic. The first time it fell only one stair, and I figured it was no big deal - their sensors are supposed to prevent them from falling, after all. The next time, though, apparently it got a bit too far over before the sensors realized, because I was sitting in my room and heard KATHUNKA THUNKA BAM BAM. I knew immediately what it was, and the Roomba soon chipped in with it's vaguely sad error/stuck tones. I literally laughed for about 60 seconds. Fortunately, it's still in operating order.
In other news, I flew back earlier today - I'm at Tech trying to be productive...hopefully that will go well.
