He finally got it.

So after five months of telling Mason to get out of Elly's face she finally spit up on him. I had to laugh when I saw him. He of course was crying. It was impossible not to laugh because I have told him she was going to do this to him for along time. He finally got what he needed. He stayed out of her face for the rest of the day. The next morning he had forgotten all about it and was back to being right in her face.
