This happened a few months ago:
Deacon was wiping syrup from his mouth onto the sleeve of his shirt and I asked him not to do that. He said, "What (pause) ever. Nobody needs napkins."
Not sure where he learned 'whatever'....
Then this happened this week:
Deacon didn't know I was watching him but he started to wipe his mouth on his sleeve and then just stopped. Then he looked up at me and noticed I was watching him and then I asked him if he needed a napkin and he said yes (progress!). Then, two days later we were having lunch at the table together and he started to wipe his mouth on his sleeve again, but instead reached across the table and grabbed a piece of paper (!) and wiped his mouth with it. Then he started laughing hysterically because he knew paper is not for wiping ;)
