I dunno... I met a lot of dimwits in grad school. Had to do "team" projects with them too... like anywhere else and like in bidness... a couple of people drive the project and the rest just hang on with the minimum.
So what if there's no "I" in "team". There ain't no "you" or "me" there either. :-)
There's a "me"... for "this is my grade we're talking about".
It's just not nice that some people have four hard-working members, while we effectively have two.
