This is possibly massively outing.
DH and I went to a well known swedish furniture store today to pick some bits up. Our DD (9) didn't really want to come and I was having a text conversation with a good friend whilst we were discussing it. Friend mentioned she was having a day at home and I cheekily I suppose asked if DD could come over and play with her DS (also 9) for a couple of hours. She said yes and I thought nothing of it. DD and her DS are good friends - he's often come here to play including full days in Xmas hols when I am not working and his mum is.
Dropped her off at 11 and picked her up at 2 so 3 hours in total - she did have a sandwich there but I'd also packed her off with some malteasers to share with DS's son. They spent the whole 3 hours playing Lego.
When I picked DD up my friend asked me if I could have the £20 for her tomorrow as she's a bit skint
. I asked "what for?" and she said "babysitting- it's normally £10 per hour on a Sunday but as she came here I'll do it for less". I said yes because I was a)embarrassed and b) shocked. I never would have asked anyone to actually babysit so we could go shopping - I thought she was doing me a favour 
She is a childminder for her FT job but she's not my DD's minder. DD goes to school with her DS and I see mum socially without the kids normally to get drunk. Thinking about it DD has never been there to play without me but like I say her DS has been to our.
AIBU to think I was asking for a playdate hate that termor did I actually ask her to babysit?!
