lack of manners
When someone acts like they're the king of the universe and everyone else is just there to serve them.
At the buffet, my kid took the last plate and said, 'This is my kingdom.' I'm not even the king.
My friend’s kid tried to take the last cookie and said, 'You're not my friend.' I'm not even his friend.
My kid threw a juice box at the waiter and said, 'I don't want no more water.' Like water was a curse.
