The Traffic Light
"Red light, red light, what do you say?"
"I say stop and right away."
"Yellow light, yellow light, what do you mean?"
"I mean wait until the light turns green."
"Green light, green light, what do you say?"
"I say go, but look both ways."
"Thank you, thank you, red, yellow, green,
"Now I know what the traffic light means."
