Kindergarten Memories

Way back in the day [the days of naps, storytime, and DickandJane], when I was kindergarten, there was a lady who came to talk to us about brushing our teeth. Now, maybe I'm just dellusional and replacing fact with fiction, but I think it really did happen. She was probly one of the kids' moms and happened to be a dentist so she came in and talked about her job. Michael's dad was a pharmacist, I remember thinking it would be boring to be surrounded by medicine all day. I think my dad even came in and talked to the class about his job (maybe I had a dream about this and just think it's real [I hate that when that happens.]
But anyhow, so this lady told us that we had to brush our teeth a certain way, it was either up and down or back and forth. But i can't remember which it was! I was thinking about it tonight as I brushed my teeth. I wish I could remember which way she said to brush...
....What if I've been brushing my teeth wrong my whole life? Maybe that's why I've had nine fillings, hmm.

-Have you been brushing your teeth wrong?
