Booger appetizer

5th grade class - Kid thinks he is totally invisible and while one student is giving a report presentation, the kid is going to town. In my head, I am thinking, "No way. He is going to rub it under his desk or on his pants, right?" Nope. Apparently, he could not wait to lunch. He decided boogers were the appetizer that would hit the spot. Finally, I had to go by and tap his shoulder (I didn't want to call him out and completely embarrass him), but he acted like I was totally interrupting some precious moment he was sharing with his nasal passage.
