Pick a finger, any finger

As a diabetic I have a favorite finger to prick. It just so happens to be my middle right finger. Its like a giant FU to diabetes. I don't know why its my favorite, it is just my go to finger. Maybe because its the longest and it just hangs out there more with all of its callouses. I don't know why but it seems like I over prick the fingers on my right hand which is odd to me due to the fact that I am right handed. Wouldn't it be easier to do the lancing with my right hand, and prick a left finger. I hate to do my pinkies, it freaks me out. I like to think that I just don't like picking (or pricking) on the little guys. I wonder if anyone else has fingers preferences?
