So the past two days, I couldn't help but notice that somebody's coming around my house either late at night or early in the morning... just to tap on my windows...? I mean, what the hell? I don't think they're trying to break in, so I don't quite know how to respond. I keep my Wakizashi close at hand, but what can I do? He's not trying to break in my house, so I certainly can't go lashing at the guy with a sword, and I doubt the cops can do anything. Anyone have any ideas? Or have a similar tale to share with the rest of the class?
