lack of manners
When someone forgets how to say please and thank you, and also how to breathe.
My brother asked for a second slice of pizza and just said, 'I want it.' No thanks. No please. Just a demand.
My friend’s kid tried to take the last cookie and said, 'You're not my friend.' I'm not even his friend.
At the restaurant, the kid threw a napkin at the waiter and said, 'I don't want no more water.'
