Little red man, what do you think of?

ooh I've never noticed before the little red man's impatient looking stance.
Not happy go lucky like the little green man who strides in his strutting pose.
I wonder what they talk about when no one is around?
Do they argue & fight? or do they talk about the traffic?
or discuss what they really wanted to be?
Are they scholars or literature, poetry, are they mathematical geniuses?
or are they just what they are, watching us cross to and fro at the traffic lights?
