Most people at med school are really nice, caring, down to earth people. You're painting with a broad brush there, and it's a terrible misconception you have.
Just being honest. About 75% of the entire population of med students I've had interactions with were overtly arrogant, thought they were God's gift to mankind, and seemed to think they were more important than everyone around them (Yes I realize those were redundant descriptions, but I'm really trying to hammer the point home here).
To be fair I may be exaggerating a bit. But not by much. I have a very poor view of doctors though, as a result, and which admittedly is a broad generalization.
But hey, if the shoe fits.
