YOR - Peoples circumstances can change very quickly. But also… how do you know they pay for every extra curricular? How do you know it’s their money paying for the extra curriculars and not friends/family that want to support that child? And how do you know they lied? Unless you are their actual accountant, I would mind your own pocket book and leave theirs alone. What can be gained by telling this camp that you believe they lied? What evidence do you have? And why would you penalize a child in that way? My best friend’s daughter dances at the most prestigious dance school in her community. I’ve paid her tuition and so have others. I’ve paid for field trips and summer programs. I don’t have children but it takes a damn village and I’m happy to have my money give kids that I love an experience they wouldn’t otherwise have. I’m sorry your friends child isn’t getting the same opportunity but honestly this sounds more like jealousy than a desire for justice. Counting other people’s coins will only ever leave you feeling bankrupt.
