I've often been tempted to get a vanity plate. Sometimes I really thought that a certain word was really ME, and would look great on the back of my car. But: the extra cost, laziness, and the fear of identification always held me back. The fact is, there's going to be some moment when I really don't want the other driver to remember my license plate. How would you feel, and what would you do, if the driver that cut you off had a license plate you could remember for ever?
So let me suggest the vanity plate above. I think it says: Oh, I like you.
