['I had to work with a partner for my senior thesis and he did nothing! Do you like group work?', "Oh I hate group work for that exact reason. I'd rather just have company while I did the work", 'Me too! I spent months on it and we ended up with the same grade.']
What a shame. I wouldn't make them my partner again. (and I might venture so far as to notify the professor)
I hated group projects but when I had to work with a partner for my senior thesis and he did nothing. I was so mad, I spent weeks on it and he took most of the credit for it.
