I recently saw in a movie, "Jeremiah Johnson" (the one from 1972, with Robert Redford), in which Johnson marries a woman unintentionally by sipping from a bowl that she offered. The tribe considered this as evidence that he accepted the woman as his wife.
Has one been able marry unintentionally in any society?
Is it at all likely that such event happened, based on any records of such an event that may exist?
Or is it valid to assume, that such thing likely not happened, because cultures take the ceremony of marriage seriously?
Would such cultures normally recognize and excuse such an error?
P.S. I am not a native English speaker; I want to explicitly declare, that I do not intend to offend anyone. If I do, I beg your pardon.
