To whomever mentioned that saying Good Shabbos can lead to flirting: does that mean that when I say Good Shabbos to my father’s friend, a guy who’s married and has seven kids and three grandchildren, that can lead to flirting?
My mind honestly rebels.
There are gedarim and there are gedarim for gedarim and there is a concept of going too far. If you flirt with a girl, it’s NOT because you went to say Good Shabbos to her- just a shot in the dark here, but could it possibly be vice versa?
