My friend and I have a very give-and-take relationship which usually works well for both of us.
She will have mine for the school run and after school for an hour if I am working overtime and can't get my childminder on the days I don't normally use her. (My girls and her girls are in the same classes as each other and are firm friends.) Usually just on the odd occasion, not a regular thing. E.g. 4 times this year.
I order stuff for her if she doesn't want it delivered to her home if it is a surprise for her partner or kids birthdays - and gone to depots etc to collect them even though I work days and she doesn't. I've helped her move home. I've given her lifts when her car was broken and my husband fixes everything that she brings round that is broken. We take each other's girls to parties if the other one can't make it. I'll pick all manner of stuff up for her from the shops on the way home from work.
You get the idea....and normally I really don't mind. But...
She's got a new job that involves antisocial hours. I babysat for her girls last Fri evening while waiting for her partner to come home from the social event he was late from even though he knew she had to work.
I've had a request to babysit again this Sat from 5pm til 1 in the morning. Eek. I don't do late nights even in my own home and won't be able to settle in someone elses house. Also, I haven't asked, but I think that her partner is out socialising again, not working, which makes a big difference in my opinion. He doesn't like her working evenings and is making it awkward for her. I don't like the idea of leaving my OH at home with my girls all evening for me to go and sit with someone else's girls instead of my own.
I'm getting worried that this is going to be a frequently asked question. And when I said I could help on this occasion, but was concerned it was a late night, she pretty much replied by text "well I'll NEED you to help more in future" as I think she and her partner are calling it a day and then she'll have no childcare as he will be moving down South if they split up, leaving her with an evening job and no formal childcare.
Arse. I'm usually happy to help out any of my friends. But am worried that this is going to become a pattern - and I'm rubbish at saying no. Especially as she knows I have no social life of my own most weekends
