I don't let him lick my plates but my parents do when he's over there. I really don't like it. I'm pretty lazy and I usually eat in front of the tv, so I often put plates on the floor or on the couch even when I'm not done. I don't want him thinking that every plate is for him, or that every plate might be for him. He's also very tall, and it's no sweat off of his back to put his head on the table without having to jump up onto it and nab something off a plate. Plus I think it's gross, even though they go through the dishwasher. I don't let him lick my face either.
