Bea, He wants to look good in the eyes of his younger son, but on the other hand, he's calling you to task for a small amount of money. It's the mlc mind hard at work. I can remember when my xh called me to task about a gas credit card charge of $10 and wanted to know when I was going to reimburse him for it. Now, keep in mind, I had just paid for a complete tune up of his vehicle and his lawyer's fees on two joint credit cards about 4 weeks after he left.
Bottom line, it doesn't matter how much they spend, but they sure as h@ll want what they think is owed to them. I don't blame you for calling him on his behavior. $38 is a drop in the bucket when you think about it.
I hope and pray that things go well between your son and your xh today.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
