Found out today that dd (16) had had her boyfriend over at our house today without asking me or telling me. She called me on the phone while I was out to find out when I'd be back but didn't mention he was here. I've met the bf once - he seems fine, nothing against him, but I'm not happy that he's coming round without my knowledge, in her bedroom with the door shut, and dd lying to me about it. I've grounded her till she starts school - only 2 days as she starts on Fri.
AIBU here? She did know that I wouldn't be happy with this. The house was in a complete state so she blindfolded him apparently (!!) - yes, not making this up - rather than eg bothering to tidy up at all. Dh and I are working long hours at the moment, dd is doing nothing, so am quite annoyed that she's doing nothing to tidy up and inviting people round without notice. We're not a family that has an open door policy and never have been - we live in a rented property that usually needs repairs and redecoration the landlord won't do, so although the kids do have friends over, we do then make an effort to tidy up first. Plus I'm not thrilled at having the two of them in her room with the door closed when I'm out - sure lots of people would be fine with that but I'm not and dd knows that.
Perspective on this please?
