Money, money, money.....Money

Ex-son-in-law owes us some money. Don't really care at this point and time. We really like the guy (as does his ex-wife, but only as a friend). Though it did come up in conversation recently. Daughter and the Princess were discussing the fact that her dad (the xsil) "loaned" her the money to buy some  special tennis shoes she needed for volleyball. He wanted to teach her a lesson about money. Well, being that we were in a car together, Pan and I couldn't help but overhear the conversation, especially since the Princess didn't think he was being fair. Our solution..... Tell him to deduct it from the money he owes us (maybe that would be a good lesson for him, huh?)
