A friend of mine once told me that his engaged girlfriend in another city needed $800 to fix her car.
"She'll pay me back", he said.
"Not only will she not pay you back", I told him, "but she won't even answer your calls"
I said, "Give her what you can afford to loose, but not all $800"
He didn't, he sent the whole thing.
She didn't answer his calls for six months, to breaK up.
She didn't even mention the $800, either, but she did say she had a different car.
Since she didn't actually benefit from the loan, she decided it never happened.
