So I was in my economics lecture peacefully taking notes on an interesting lecture about oligopoly by Professor Gateman as some “delinquent” (as Gateman calls them) walks in late and finds a friend who happened to be sitting on one of the seats on my row and settles down beside the friend. The latecomer is offered Cheerios from the friend and proceeds to munch and crunch on a small box of the cereal for the next half hour, not noticing how loud the crunching sound really was, not noticing how the other student sitting on the other side was covering his ear, not noticing a student a couple rows down looking up trying to figure out where that crunching was coming from. Really, I wouldn’t mind if the consumption of the food does not produce sound, but *crunch* *crunch* *crunch* continuously during a lecture just annoys me.
