I work Sundays. Have to be up at 5.30. Step kids are here every Saturday night and the eldest (18) likes to play guitar/computer games/chat loudly over the Internet until early hours which keeps me awake. Dp says it's unreasonable to ask an 18 year old to be quiet on a Saturday night. I however feel that at 18 he should consider the fact that people in the house have to be up for work so 11pm isn't an unreasonable time to tone down the racket. What do you reckon?
