Traffic lights

On the way to the movies Nate was explaining to Ashley how there are fruit loops in the traffic light that make it red and green. They are fighting, and when the red one is winning the light is red, when the green one is winning the light is green.
Ashley tried to tell him it was a red circle with a light, but he didn't believe her. He is sticking to his fruit loop theory.
Ah the workings of a child mind. Wow.
