Never underestimate the importance of lefty-friendly scissors OR non-smearing ink (as a lefty's hand passes over what he/she has just wtitten). I have yet to find a good lefty can opener.

My son and I are both lefties but COMPLETELY different in talents: I am very artistic/creative and he is a wiz with math/science. We are both very strong visual learners though, in stark contrast to my "hear it once and know it" righty dh.
