We have a lovely 19 YO German au pair who is really a delightful person, very nice with the kids, reasonably helpful around the house and generally seems (or seemed) like a sensible, responsible person, given her very young age.
My problem is this - she has started staying out very very late (like 2, 3 AM) during weeknights, and (I think) possibly staying out all night once or twice and then coming back in before she's meant to start work at 7:30. It seems she's met A BOY - which is very nice of course.
Now - on weekends, I don't have a huge issue with this, though ideally I'd like her to let us know if she's staying out all night so we don't worry. But - I'm not so ok with it during the week. I feel like if she has to be up and ready for work (which involves childcare and school/nursery runs for 2 little ones, so not just mindless cleaning) at 7:30, she should be home at a reasonable hour the night before, and also I just want the peace of mind of knowing that she's home and safe and that she will actually definitely be there and functional at 7:30 the next morning - it's just not something I want to spend time stressing about, iykwim.
I sat her down earlier this week and had a chat to her about this as she'd been out till about 4 the night before, and she insisted it was just a one-off as this boy she'd met was about to leave for parts unknown, and said it wouldn't happen again, and was very apologetic. BUT - I then had to travel for business overnight, got home at midnight last night to find the house asleep (or so I thought), latched the door, only to be roused at 1:15 AM by the AP ringing the bell because she'd been out and couldn't get in. She apologised this morning for waking me up, and said she'd told DH she'd be out late, but it was as if that earlier conversation about not staying out late on work nights had just never happened.
So I don't know whether I was just too nice in our chat, or whether I really have to set a firm curfew during the week, or whether I am just being unreasonable, or what. Keep in mind that other than this, we are happy with her, and given my work situation (and DH basically working very long hours so not around to provide back-up at all), it would be a real challenge not to mention disruptive for the children (who like her) if we have to replace her at short notice. But I'm not happy with this behaviour or with the fact that she pretty much ignored my "nicely" telling her not to do this once already. I have no experience with this as our previous APs just never did this. What do the rest of you do about this issue?
