One of my daughters is taking summer classes at an Atlanta college and has been astounded by how rude many of the students are. She said they take phone calls in class, chat with each other while the professor is lecturing, and frequently just walk out.
I've never encountered that in any of my classes. About all I've had to deal with has been the stupid costumes the former local groups used to make their pledges wear and I started throwing those kids out of class after the first year. (Try lecturing while girls in leprechaun outfits with deelybobbers are sitting right in front of you.)
Do many of y'all see this on a regular basis? I'm horrified. I wouldn't tolerate it for a minute and can't believe that this professor does. Coincidentally, my daughter says that the only people in class who haven't done something rude are she and the other 2 Greeks (2 Tri Delts).
