I'd aranged for me, my friend and her child out for the day to a funhouse along with one of my mindees. I'd texted her about 4 days before the outing to tell her how much the admission fees would be and also if she could contribute £3 towards petrol. She didn't reply to that txt but I'd asked her if she'd received it a few days later hoping she would mention something about the petrol money. she had got it but never said anything about it. We've just come back from the funhouse and she hasn't given me anything towards the petrol. Now AIBU to be annoyed? Should I have asked at all? How can I ask for the money off her without seeming mean? Should I just let it go?
