A distressing event

One of the students pushed me today. I know he just meant it in a joking manner, but I had to report him, because that really is completely unacceptable behavior. At the time, I was mostly just shocked that someone would be so stupid as to do that (especially as the class seems fairly evenly divided between people who think that I'm the instructor's sister vs. those who think that I'm the instructor's daughter, so either way I shouldn't be a figure to mess with), but now I'm just feeling depressed and more than a little betrayed.
