Question:
And what’s not tzniyus about familiarity between young men and women (eg sharing contact information with people of the opposite sex)?
Answer:
See the following post https://dinohttps://dinonline.org/2026/05/18/women-dancing-2/ that we commanded against doing anything that will make people of the opposite sex close to each other, ( when the relationship is forbidden). This includes anything that makes them close. All forbidden relationships start of with familiarity, and then it gets closer, until it leads to forbidden relationships. Therefore the Torah commands us to stop the proves at the beginning, so that it doesn’t lead to anything.
Best wishes
