Dentist

I went to the dentist to get my teeth cleaned. I had started flossing regularly and was looking forward to the inevitable moment of recognition: Wow, Tracy, great job flossing. I kept waiting, but it was as if he didn't notice. I brought it up as tactfully as possible - So, Dr. Mehta, can you tell I took your advice about flossing more? - but of course that wasn't nearly as rewarding.

He did, however, put in the effort to tell me I might need a crown on one of my sensitive molars.
