It's actually funny to see him walking around with this thing all the time. I don't mind at all. I suffer from a bit of OCD myself. Just in other areas that's all. I believe we all have areas in our lives where things have to be a certain way.

There's still some food lingering on the face however. I guess the dust buster can't pick up everything.
