Hmmmmmm.... you know something I don't?
Lend me a few grand and I'll tell ya. (Accidents happen, you know.)
On a more serious note, when my father-in-law died at 90 he had about $40,000 in outstanding IOU's in his account ledger. He had loaned a divorced neighbor woman with two daughters money to buy a modest car about ten years before he died (and told us about it) and she paid up punctually.
He never told us about these other loans, my wife and I knew all these people, or their parents. It was his money and he was free to do with it as he pleased. We visited him every weekend (he lived about 50 miles away.) Apparently "designing and artful" people visited him during the week.
My wife was miffed because that represented a good fraction of his estate and we had never asked him for any money. His lawyer (a long time friend and very good guy) said that the debts weren't worth pursuing.
I guess the lesson is that it pays to "befriend" lonely old people who have a little money in the bank.
