Hah. First experienced this as a kid when helping out at my mom's jewellery shop for the first time. Someone bought something and I had to calculate how much cash to give them. I don't know why I wasn't using a cash register, can't recall. Anyway, I'm really good at math, yeah? One of the best in my grade, yeah? Then why couldn't I calculate how much money I needed to give the guy? I did this kind of subtraction problem in my head all the time. But I froze. I felt so stupid at the time. :) STOP STARING AT ME, I'LL GIVE YOUR MONEY, JUST WAIT A SECOND!!!! :) Funny thing is that he probably wasn't judging me at all, it was all just in my head.
