I recently witnessed two people, obviously friends, greet each other. One was a lovely woman, the other a nice-looking man. 

Instead of shaking hands or sharing an innocent kiss, as one would expect in these situations, the man gently touched the woman's breasts. His hand simply did so on the fabric covering what looked liked beautiful jugs.

The woman, perhaps in her  late 40s, early 50s, did not bat an eye by this attention. She smiled and engaged in an antimated and friendly conversation.

 I apparently have missed a lot in my life. I had never before seen such a display of affection in public.

One would think that this kind of "greeting" would provoke protests, even accusations of assault or sexual harassment. 

Is this a common greeting among some men and women? This blogger hopes he receives some comments. Thanks to readers in advance for responding.
