Oh, I've been the source of much amusement for many people over this issue. In a car, when I'm a passenger trying to give directions is when it's most apparent because of course, drivers hate it when they ask, "Which way?!" and you, as passenger say, "That way!!" frantically pointing in the air with your finger! (They don't seem to appreciate having to take their eyes off the road to look at where you're pointing.) So...I've learned to SPEAK instead of gesture, only there's about a 50% chance I'm going to get it wrong--and then, of course, the driver is mad at me again! lolol

I used to know my right from left very well, didn't have to hestitate--but that was because I had a mole on my right arm. Then, when I was about 12, I had it removed and it's been downhill ever since! I really have to stop and think now, which is which. Pain in the neck. I'm right-handed (very).

Good to know that others are being chuckled at also, their overall intelligence questioned because of this one little quirk.... maybe their just jealous because they're not brilliant and good looking like us.
