I'm laid in bed and about to settle down, I can hear my 18 Yr old DS in the room next door laughing and talking while he plays a game. He can sometimes do this until 4am with friends. Some nights he is louder than others and it causes arguments as it disturbs our sleep- he doesn't realise how much louder his voice is in a quiet house and argues that he isn't being loud.
It's hard to give him a curfew for this because he's of adult age, but equally he's acting like a child not considering others.
I don't understand how his friends can do it to without annoying their parents or waking siblings!?
