When I was a LOT younger I thought cat calls and being whistled at
was very disrespectful.
Now it has been several years with no whistles etc.
I think if someone where to whistle at me at my age,
I would be insulted because I would think they were either
blind or needed glasses. lol

I think a nice compliment from a stranger that appreciates
the way you look is much more polite than
cat calls and whistles. JMHO
