Same basic behaviour, two reactions

My GIS TA is in general incompetent, bitchy, and weird, so I find it really irritating that she doesn't staple together our assignments - we just get sheaves of paper.

My health econ professor on the other hand is funny, smart, and generally on top of things - so I find it endearing that he keeps giving us stuff stapled in the lower right-hand corner.

Huh.  I am being inconsistent, possibly double-standardish.  Oh well.
