Things have sure changed since I was in school, and I graduated in '93. I can't even imagine speaking in such a way to anyone when I was a kid, but especially an adult, or rolling my eyes at them. Maybe it is just how I was raised, but I certainly thank my mom for that. I always try to be respectful, even if it is not being reciprocated. It will just get you a lot farther in life with people you deal with on a day-to-day basis.
