Damn, I know the feeling though. When I divorced the first wife she went on state and immediately put me in arrears with them. Imagine, the state gave my wife the money to take my kids and abandon me and THEN
I had to pay it back. Every year for I don't know how long them SOBs took my refund.
I used that same line on a child support judge once when the state had called me in on not being able to afford medical insurance for them. Two state workers standing right next to me. I'm pretty sure they were looking for a table or a rock to crawl under right about then. I won BTW, I had to add the phrase "at a reasonable cost" to the "Will provide medical insurance" clause. The insurance available to me for the kids at the time cost pretty much what I was making and they wanted me to pay it. There was no way...
I also got to stand her up in front of him and mention the fact that she'd been on state for 8 years by then with no intentions of ever getting off. He looked at her, said, "Eight years?" and shook his head. Yea, that was a good day for me.
Sorry, I digress.
