Vibhu and Venky were driving to his school. The road was fairly empty. They pass through a traffic signal.
Venky – “Papa, was the light green or red?”
Vibhu (irritated that Venky still does not know his colors) – “Don’t you know colors yet? It was red!”
Venky – “Papa, then why did you not stop?”
Next time we were driving through an empty signal and the light was red, Vibhu applied the brakes right on time.
