People you don't know

Then what is money?

Money is the opposite of love. Or, money is the power to get people to do what they don't love. If you love to do it, you don't care if you don't get money for it. If you don't love to do it, you'll do it only in exchange for other people doing what they don't love, and money is the tool for doing this kind of exchange with people you don't know.
