I find cutting someone else's child's hair without permission to be absolutely inappropriate. And I agree that at this point it's time to get out of there asap, because your kids are not old enough to be able to distance themselves. um, I would freak if my partner, and the father of my kids, wasn't allowed to be in my parents' front yard without them present. it's the front yard, what are you going to do? I can see why not in the house, but the yard?
I can't. She's a grown woman, with children. This is all entirely nonsensical, and nothing more than manipulative and controlling. Could her parents reasonably put their foot down about the boyfriend spending the night? Yea, they could. It seems silly to me, but it's how some people feel. But..... the front yard?! Or the living room, with the kids around? Geez.
People draw the line different places. there was a time when I wasn't allowed to be alone with my BF in my mother's house or even in a room alone with him while other people were home, and she isn't deeply religious or anything. and I wouldn't count young kids as chaperons, too easy to have them in another room, so while I think it's over the top, and somewhat controlling, it wouldn't be as huge a deal. but him not being allowed in the yard is way over the top for me.
