Just wondering what would be acceptable to others. Im a lone parent to 4 sons, second son has just turned 18. He has rolled in at 3am or later several times already this week and intends to do the same tonight and tomorrow. He's just hanging out with mates, he was the last to hit 18 so is making up for lost time going to pubs/clubs. Its very hard to switch off and sleep when he isnt in, my elder son was more considerate and had lifts home at that age. This child walks for miles on his own and has no apparent concerns for his personal safety. He's a man I know but to me he's still my little boy. I dont want to argue with him just wondering if others have rules for adult children.
