For reference we have 3 teenage girls, all own rooms and different friend groups.
I have a fairly open door policy but after hosting my parents who stayed last weekend, a teenage friend of my eldest being here all day Friday past (11ish to 7pm) joint friend of two younger DD’s here yesterday and over night, They have been out all day with their horses, just all piled back in and DC has just asked if friend can stay for dinner and over night again.
I hate saying no but my younger daughter 13 and I can tell looking at her she is exhausted and sometimes it’s nice not toe worry about being appropriately dressed when you go for a wee in the middle of the night and also have a quiet/er house in the morning.
DH would say yes to everything and makes me feel like a complete fun sponge when I say I’m not really up for it.
