It is so much fun when in the middle of an innocent conversation I correctly guess someone's Blood Type. They look at me like I'm psychic. The resulting conversation is always interesting.

I am at my Mom's house for a couple of days. Her caregiver had to go out of town. The last time I was here Mom said she thought she had a cavity. She was right. Actually she had three. All are small. Two were filled today, and we'll go back for the third in March.

While I was waiting I asked the receptionist if there was a place nearby where we could get barbeque for lunch. Mom and I - both Type Os - were hungry for some good brisket. The receptionist rolled her eyes. It turns out that the dentist loves meat, but she doesn't. When he wants to take the office staff out for a treat, he takes them for barbeque. She said, "They have really good sauce, but I just don't like to eat meat."

I said, "Do you have Type A Blood?" She looked at me like I was crazy, and said, "Yes, but how did you know that?" I had fun telling her about the Blood Type Diet, and I wrote the web address down for her.

Then the dentist came out, and the conversation got even more interesting. He loves meat, and he feels guilty about it. He believes meat is bad for everyone, but he can't help craving it. I kept thinking that he had to be an O, but when I asked, he said he didn't know his Blood Type. Rats, I wanted to be two for two.

After the appointment, Mom and I drove to the restaurant. The line was long, so I felt sure that the barbeque would be as good as the dentist promised it would be. We were not disappointed!
