I actually burst into laughter yesterday as I passed by Office Guy's window. He moved a whole foot and a half to watch me pass and this time with a smile. His first one. He finally got his timing right. The only thing is that he closes his blinds too early in the afternoon so when I walk by after my lessons he's hiding behind his blinds. Or maybe he doesn't work in the afternoons, maybe he only works part time.
I'm a little worried he's going to try to talk to me at some point.
