I have a bad habit of accepting free stuff. Free socks—they’re brand new, still in the packaging. Not the color I would have bought, but they’re free. It’s a trap. Something’s being cheap is not a reason to buy it. Something’s being free is not a reason to accept it. It depends on what the something is. Try this: Free car. Free car that doesn’t run. Free dirt. Free dog. Free cat. Free elephant.
