I know this most probably sounds petty to some compared to their own problems but I'm so annoyed.
DSD lives with us and just before half term came home with a letter for a school trip. She told her mum about it and she (mum) told DH she'd pay half as long as he can wait until the weekend just gone as that's when she next has money. Fair enough. Queue the weekend and DH received a text that she couldn't afford to pay half. DH text asking is there anything she can put towards it - even if she can give it by next week (it doesn't necessarily have to be half) and he was responded with: "No, I have a girls night out planned for next weekend so no can do."
This means that she has let DSD down again because she promised her she'd be staying there next weekend but also we've had to pay the full amount (which we would have if she hadn't had said anything) but it also means the meal I was meant to be going out for this coming weekend is now not happening as we literally can't afford to pay for the full school trip and go out for lunch. We also have 3 daughters ourselves together to support so money can be really tight with everything that has to go out.
