Too close for comfort

Today Jax and I had another great pilates session. Evy always comes downstairs to get us around 5:00, because she always drives. Pilates starts at 5:30, so we usually leave at 5:00. Jax happened to wake up from his nap at like 4:40, so he was in such a great mood the entire class. I was so happy because when he's in a good mood he doesn't hang on me the whole class. He crawls around, plays with all the equiptment, plays with all the other women in the class and sometimes just sits (for a few minutes) and watches us exercise. I was so proud of him for being such a good boy! When class was over, as we were just about to leave, the people from the class after us were coming in. There was a lady that came in, who we have seen once or twice before. She was probably in her 40s or 50s, so she obviously either has children or has been around enough children to know NOT to do this. She takes Jaxson's hand and starts kissing his palm, and then proceeds to do the whole "spit" thing in his palm as well. I was so grossed out. Lady, don't you know kids put their hands right in their mouths?!? Well I happened to have sanitizer in my hand, so i grabbed his and rubbed it down for like 30 seconds. For real, who does that?
At first I thought it was a greek thing, but when we got in the class Evy was like, "why would she do that"?!? Well I was wondering the same thing...people keep your spit to yourself. Thanks:)
