Uh?

This has been a really uneventful week and the only item of note was this:

I was walking down the street with Astin on the way to play frisbee. We walk past this guy who fakes like he's going to hit me in the face with his folder. I felt the wind whoosh past me. I was completely dumbfounded and had no idea how to react. Who does that? Finally, it occurred to me that it might be Graham, so I turned around to double check, but no. The guy was still walking up the hill but looking back over his shoulder to see my reaction. I think what he thought was one part total surprise and one part disgust. Weirdest thing.
