Hello Glynn. Whether or not we believe in "gaydar", I do think there is something to be said about subtle or coded body language.
Sometimes, I do think such protocols can be subconsciously driven, triggered perhaps by some primordial instinct or mating pattern in early humans.
But to be sure, sometimes, we just take a chance.
I will not be too confessional here, but I do think sometimes, our attraction gets the better of us and we proceed to act in a "hell come what may" attitude. Even in the cities, this can be dangerous, but we sometimes do it nonetheless as a calculated risk. At stake is our own personal desires.
Perhaps this was the case with Jack...
Perhaps not...
