Agreed. They sound pretty lousy.
My parents paid for my education too. They saw it as their responsibility; sort of the last helping hand out of the nest. Thing is, I still worked. In hindsight, I shouldn't have, but I did. I don't like playing the 'what if' game, but I'd imagine that I would have at least had a higher GPA if I was not working. Probably would have been able to go straight into grad school too. Ah well. The point is: don't let these little people bring you down to their level. Smile, nod, and know that you'll never have to deal with them again, soon enough.
