Right and left are so totally obvious to me, that it really mystifies me when someone gets confused between them. The concept of right and left comes from within a person...while concepts such as east and west come from outside a person, so it's a whole different kind of thing.

I can sometimes be in doubt about compass directions, if I'm driving around downtown on unfamiliar streets, but get confused about right and left?...never. To me, they are as obvious as up and down...although not as different in their effect, of course.
