A great comeback would't been, "But your hair smells so nice."
I was in the usual standing-in-line reverie. It was such a shock I wondered for a minute if maybe I had gotten too close. There are guys who get off on rubbing up against women in lines or on buses and such.
But I am most certainly not one of them!
One time I was in Walmart and going from one department to another. Apparently a woman was going the same way.
She stopped and asked me,"Are you following me?"
I replied "No but I will if you want me to".
