Went out last night with a group of friends, it was a little last minute in organisation because we've been away on hols so I had to get a babysitter at the last minute, so used Sitters, who are great, and they sent someone I hadn't used before, which is fine, they are CRB checked and mostly childcare professionals of some kind (this one was an ex-social worker) and my children are a little older now so no big deal.
So, to set the scene, like I said we'd been away so in my upstairs study I had my week's worth of dirty washing of my own (I'd put the children's stuff through the night before and during the day) and my husbands stuff had mainly been done.
When I got home from our night out, there were clean ironed clothes hanging everywhere. On the sofa was all my dirty washing from my bag in the study washed, dried and folded, including my undies (and cringe - some period pants that happened while I was away that were separate in a plastic bag that in all honesty I probably would have binned once I got round to sorting through).
Because we'd been away for a while I had some of my less good undies in there too. In fact I could do with a sort out of stuff
Of course she meant well but I was MORTIFIED! Though I tried not to show it. At the point I first noticed washing about I hadn't even quite realised the extent to which she must have gone digging for washing - at first I thought she'd just taken it upon herself to fold some of the clean washing basket that was languishing in the utility room but after she left I had a good look at her stash and realised she had been upstairs particularly when I saw all my stuff there!
Also, she had found hangers and lots of them, which means she was in our room and probably opened my heaving full of several different sizes wardrobe to pick around for hangers! 
My son told me she had asked him (after he had gone to bed) for hangers and he had gone in our room with her.
Bless her for trying to be nice but I'm paying minimum wage for what should be an easy gig - sitting on my sofa watching my tv while my children sleep. As much tea, coffee, stuff out of the fridge or toast or whatever you want. And I expect nothing else other than you keep my children alive and tick the box that is not leaving your children unattended by paying someone to sit there!!!
I just felt slightly ...violated? I just didn't expect someone to go upstairs and through my bag and my stuff and in my wardrobe...I just feel that my mess is my mess (and its usually in reasonable semi-chaotic but clean order except I'd been away!)...
AIBU to be a bit about this or should I just be grateful and get over it? Can't do anything about it now, of course! Husband was miffed and embarrassed and mentioned it to my mum on the phone and she' was a bit "WTF!"
Discuss!
