My father, who is an extremely generous person, gives away his old cars when he upgrades. I think the most recent recipient was daughter of a former coworker who was going through a rough patch or something like that. Years ago, when my grandfather decided it was time to stop driving, my father offered my brilliant but lazy friend his car for free (old, but few miles on it, since my grandfather didn't go too far), hoping he would use it to get a better job or something. My friend didn't even have his license at the time, didn't want to get it, and turned it down. (I told you, brilliant but lazy.) A mutual friend whacked him upside the head, saying, "FREE CAR. What is WRONG with you?"
He's helped bail out a few of my less fortunate friends at times over the years (help with rent, car repairs, etc.). But you'll never see him on JJ because he's smart enough not to expect to be repaid, regardless of whatever people might promise.
