Don't talk about gross things
Don't ask for seconds before others have had firsts
Don't take more than your fair share
Don't overload your fork or plate
Don't gobble your food
Don't chew with your mouth open
Don't talk with your mouth full
Don't play at the table
Don't hum or sing at the table
Don't tip your chair or lean on the table
Don't eat with or lick your fingers
Don't push your plate away when you're finished
