whats with my birthday

Had doctor appointment today. Needed a B12 shot and prescription. As I went in with the nurse I was asked my age. I come there every month and its on my chart so whats the deal with that. Then as I went in to have my bloods taken at the same doctors office, the girl asked me my birthday. I lied even though I saw it on the paper she was looking at. It was in big letters, but she just had to ask to be rude. She said she'd have to ask the nurse since it was wrong. I got a call when I left from the doctor so it must have been about my birthday. Why don't they ask my name each time too. I've been with the same doctor for 12 years and I don't want to be asked my birthday or my age one more time. . Or maybe I'll tell them the name of my blog...aging backwards. Better yet, I'll just take a year off for each birthday that comes around, and tell them my new birthday year. Hope they don't think I'm going mad.
