No curfews as at Uni.
But definitely courtesy of telling me if they will join us for dinner, aren't coming home, and a quick text "home" so I can have peace of mind if I'm wondering are they in at 3am etc.
Mine are mostly moderate drinkers.
Heads up if a friend needs a bed, but I have everything downstairs ready for them to pull out if they do.
Thankfully no issues with consideration re noise coming in late at night, but extra toothbrushes downstairs in the loo for those nights really help..
I suppose having a calm conversation re the noise and how it cannot continue would be a start.
There would be consequences to me being tired from being disturbed, like the use of No to doing anything for him.
The gym wouldn't be paid either if it continued.
It's not youth that would cause someone to be persistently noisy and disturbing other people in the house, it would be a basic lack of consideration for others.
If he's out late and noisy, then early morning ruckus of the radio would give him a nice similar taste.😁
I actually would come fown very hard on him being unkind to a sibling, completely unacceptable IMO.
Kindness to each other is very important.
Likewise if the 8 year old is being a pest, it needs addressing.
