What a great way to loose a good friend. Shame too, I'd much rather have a house full of friends than a bank full of money. But it seems like a rule written in stone that if you end up loaning someone money you'll end up loosing a friend in the process.
Next time, I'm just going to call it a gift and not take anything but no for an answer. Too strange otherwise.
My father always used to say never sell your car to a friend, in the end you won't have either one , and I think that's sort of the message here too.
