Re: I had the reverse situation
When I was an apprentice at a large motor manufacturing company, there was one young fellow on the course who was not exactly worldly wise. One day, in Basic Fitting, he asked the instructor why male and female threads were so named. The rather fatherly instructor put his hand on the boy's shoulder and said "I think you had better go and have a talk with Sister Amos". Sister Amos was the nurse in the first aid section of the school.
