Only 7? Analyze each. How much? How much embarrassment? I'm guessing you'll decide to fess up to a few and they'll be happy to pay again.
About '95 my neighbors asked me if I knew what happened to the cash and checks that disappeared from their garage. $2300 for cub scout popcorn sales. She tried not to imply that I might have stolen it. I understood her mindset though. My kid sold over half of the total. ( possibly the cutest cub scout since Linda Ronstadt) . So I split it with her. Somehow a rumor started that all the money had been stolen, so a very wealthy real estate developer donated $10k. It all worked out fine!
