I guess is technically possible to “hang out” with the opposite gender without pleasurable conversation or flirting, but that is extremely unlikely to be what is occurring.
I agree, but it is possible to “hang out” next to a group of the opposite gender without any conversation.
Personally, I like the idea of having separate Pizza shops, especially on Motzei Shabbos. All Bochrim can go to shop A, all Bais Yaakov girls to shop B. All dates to Shop C (formal attire required). Seniors to shop D (AARP card check), and families (certified with Kesubah & birth certificates) to shop E.
Are there five pizza shops on Ave. J?
