IRR-Internal Road Rage

IRR, this is what happens to me when I approach one of those Round About deals in the road. I'm not sure why I can't wrap my brain around them.  There are a few things that tend to throw me off.  Like for some reason, I have it in my head that when I want to go down the road to the left of me I should turn left. Right?  No, I have to reroute my brain to the new idea that left means go right,  then straight, then right, all to just wanting to go left!!  How does anyone come up with an idea like this? I've decided that there are people out there with way too much time on their hands. Or, and this is much too painful to accept; that it's just me and my elevator doesn't go all the way up!  My husband says it's just me, but I refuse to accept that!  Where I come from, left is left, right is right, and straight is straight.  Maybe it's just a case of Dumb and Dumber!  Hmm, I wonder which one that makes me?
