Courtship instead of dating
Before humankind began to gather in clans and tribes, what passed for courtship was likely a raid on a distant group of humans that resulted in the capture of a woman who was forced to participate against her will in an instant marriage.
Among the Arabs of the Sinai peninsula, a girl acquires a permanent reputation of chastity and modesty in proportion to her tears and her struggles of resistance on her marriage day.
The transition from marriage by capture was much more peaceful a manner to gain a bride for a young man.
In earlier times when a bride was stolen from a village by men from another tribe, members of the captured woman's clan would set out to avenge their loss.
Strict rules stipulate girls aren't allowed to approach boys, so it's up to the males, aka the 'grabbers', to tempt the girl away from her group of friends and try to get a kiss off her, even sometimes going as far as twisting her arm.
At the climax of one young traveller couple Josie and Swanley's wedding a few weeks later, Cheyenne is seen trying to escape the attentions of one grabber, who has pinned her up against the wall outside the reception.
Among many primitive tribal peoples even today, a marriage is not solemnized until the first child is born, and if no child is born the man is at liberty to leave the woman.
