What don't people seem to "get" about you?

People who have known me for years just don't seem to "get" certain things about me.  For example, back in high school my classmates thought I sat around at home studying all the time.  They pictured me as the guy who went home and spent all his free time reading the textbooks, working on sample problems, etc.  (Needless to say, I didn't date much as a result.)  The reality was that I did the bare minimum amount of studying I needed to get a grade I was happy with, and that was it.  Most nights that meant no studying at all.  Some nights, it meant a few minutes to an hour.  I played video games and spent time with my handful of close friends far more than I ever studied.  It's hard to say how much better my high school years would have been if people had really "gotten" the fact that I didn't study any more (and in fact probably studied a lot LESS) than they did.  How about you?  Is there something about you that people just don't seem to "get" that you really wish they did?  What is it?  Why do you think they aren't catching on?
