Misidentification
Today summer classes started up. The professor for my class walks in and I can't believe my eyes. My professor looks like he can be the older brother of a particular person I don't like very much, and at first I thought it was that very person. I had a few seconds of shock and disbelief accompanied with my heart beating a little hard and then, after realizing he wasn't that person, a bit of feeling stupid over the misidentification.
