Do not argue with ladies

I am sure that the taxi cab driver learnt that it pays to keep your mouth shut is some situations.

A woman and her ten-year-old son were riding in a taxi in Montreal. It was raining and all the prostitutes were standing under the awnings. "Mom" said the boy "what are all those women doing?" "They're waiting for their husbands to get off work" she replied. The taxi driver turns around and says "Geez lady, why don't you tell him the truth? They're hookers, boy! They have sex with men for money." The little boy's eyes get wide and he says "Is that true Mom?" His mother, glaring hard at the driver, answers in the affirmative. After a few minutes, the kid asks "Mom, what happens to the babies those women have?" "Most of them become taxi drivers" she said.
