When I was in high school, I got up one morning and my mom told me to not eat any breakfast. In fact, she said, don't drink anything either, because you are having oral surgery today. She didn't tell me earlier because she wanted me to get a good night's sleep and she didn't want me to worry. I didn't even see it coming.
Today, I took Sally to the dentist. I didn't tell her last night or this morning that we were going. I just showed up at her school and asked the secretary to get her for me. She didn't see it coming either.
Sometimes, it's better if you don't see something coming.
PS - no cavaties (whoo hoo!) but tooth crowding means an orthodontist consult is in our near future
