I recall an interesting incident from long ago. One Sunday afternoon, I was awakened from my siesta by a knock on the door. A neatly dressed young lady with a hand bag slung over her shoulder, greeted me with a smile and asked, in a soft voice, if she could speak to my wife. Since I wasn't married at that time, I was taken aback. Sensing my predicament, she continued, “Any lady in your house will do, Sir. I have come to explain the unique qualities of the detergent powder manufactured by our company."
