When you were just a year old, I started teaching you colors. One of the ways I did that was to point out the colors of cars in parking lots when we passed them. You learned the colors pretty quickly that way.
Sometimes, though, you'd see a rare color that I hadn't taught and then would point at the car to ask me what it was. I'd say something like "That's a beige car" or "That's a turquoise car." You'd then repeat the color aloud to me.
Once you pointed at a PT Cruiser (see picture at above right), and in an attempt to be snarky, I responded "That's an ugly car." So you said back to me, "Ugly!"
After that, everytime we saw a PT Cruiser, you'd say, "Look Dad, an ugly car!"
