I remember my mother when I was a teenager and several phrases spring to mind.
You treat this place like a hotel,
Tidy your room,
You`re not going out in that and many more.
I vowed never to nag my children like that.Life is too short to worry about whether your child`s room is tidy.Just enjoy the time you have together because once they have left home and you are alone you want good memories not bad ones.
