I have two sons left at home. One's 15 the other is 16. We've told them that during summer that they can stay up till midnight.
Their x-boxes needs to have the sound turned off and that they need to be quiet after 11.
Every night I need to tell my stepson 5-8 times to be quiet after 11. I'll tell him and I get "oh, sorry" by the time that I shut the door he's talking again.
I've turned the power off! But my wife gives in to him.
I would take the xbox out of the room at 11 or when I go to bed but my wife won't back me up.
