to be uncomfortable with the fact that my DD was invited on a sleepover, and the parent that I know went out for the evening?

[Chrishassix]

And left partner in charge, whom I have only met briefly twice?

And didn't mention it?

AIBU to be a tad upset?

How old is DD?

How old is your daughter?

Is that why you were standing on a chair to look over the fence?

LOL was just away to ask that Narked!

But a responsible adult was present

You let your daughter stay, it's their call.

Long term/live in partner or casual boyfriend?

No they live 3 miles away.

Used to happen to me lots when I was working for Sitters. Parents would book me, I'd turn up and find they were having a sleepover with anything up to 8 kids, and the parents were going out for the evening. They often stayed out until the early hours, too.

I often wondered if the parents of the visitng kids were aware.

I would not be happy. Not so much that she went out, but that she didn't mention it.

YABU

Recently moved inpartner.

Not really known by my DD.

I wouldn't expect both parents to stay in.

If it was her DH would you feel the same?

Wouldn't bother me.

The marital status is irrevelant. I am uncomfortable that my DD was left with an almost stranger for 6 hours without me being told/asked either before or after the event.

Hmm tough one. She obviously would trust her DH and maybe she just didn't think you'd mind. I wouldn't worry too much your DD is old enough to talk to you about what happened.

My DD is 11 (just) and about to go to senior school. Up til now her friends have been a close circle. Next year she'll have new friends with un-vetted parents. I think you just have to trust people as these situations will happen more and more.

She should have mentioned it if recently moved in partner, I would be ok if it was the DH of a close friend who we knew well.

YANBU.

But I often know the Mums of DD's friends but not their Dads. But that would not affect my decision to let her stay somewhere.

I wouldn't be comfortable with that, tbh. I'd want to know the person who was looking after them.

YABU but maybe you fell of your chair and banged your head.

She probably sees him as an equal parent. Your dd is 10 it's not as if she is a baby, at that age it's just someone to make sure they don't burn the place down or eat themselves to death.

Ah find your chair OP just to make sure he aint a peado init!

When shes at secondary school you won't know any of her friends parents.

Interesting.

Not once have I mentioned gender.
