"But somehow getting [my daughter] an education has encumbered me for the rest of my life."
"Somehow"? Because, like, you had no idea that co-signing a loan made you responsible if the other co-signer doesn't pay it off? Be thankful you (probably) life in a church-owned house so the creditor can't foreclose on the home to pay off (or down) the loan.
This puts me in mind of my late brother-in-law, who once paid much too much for a Camaro and then got tired of it within six months (as he always did). He couldn't sell it for what he paid to buy it. He and my sister, my brother and his wife, and I were at my parents' house for dinner one night and b-i-l asked (quite seriously), "If my car gets stolen then I don't have to pay off the loan, right? I mean, after all, I wouldn't have the car any more so why should I have to pay off the loan.?"
You just can't be a lot more transparent about plotting a felony offense. Thankfully for my sister, he didn't arrange to have it "stolen."
