My son (29) has moved back in with me as he's split from gf. I have lived alone for the last few years and enjoy my peace. His ex has been working on a Saturday and so my granddaughter (9) is there every Saturday overnight till Sunday. They take over the living room and tv. I enjoyed the peace I had , time for hobbies that have now been put aside at the weekends, I feel like saying this is my house and I don't want it every weekend. I feel every other weekend is reasonable. I am not the parent, obviously if something happened I would step up but it's just people putting others out cos they want what they want.
