I am confused, I thought there was a shidduch crisis, young people on the street in full view of the community should not politely greet each other with a ” Good Shabbos”? In Mea Shearim, or Gateshead probably not, but most other places why not?
It may lead to mixed dancing.
Or worse, cutting out Yenta the Matchmaker. How could we be so cruel to destroy the parnassh of a fellow yid?
