An actual conversation we had in the car...
Me: Do you ever worry about invisible cars?
Me: I do.
Chris: Of course you do.
Chris: *sigh* Fine, I'll ask. Why do you worry about invisible cars?
Me: Well, what if there is an invisible car. You'll never see it! You could pull right out in front of it. Or rear end it. And then you'll be all, What the fuck was that! But you insurance company won't pay because there was no other car. Because it's invisible.
Chris: And then insurance would go throught the roof because of all the accidents.
Me: You're thinking about invisible cars now, aren't you.
