In Vietnam, a father and his once-baby son who disappeared into the forest to escape the Vietnam war were found and coaxed back to civilization after 40 years. Those participating in the return have to keep an eye on the son, now in midlife, because of an apparent desire to get back home ... in the jungle.
Sometimes I wonder if everyone doesn't have some whispering sense that one day they will be discovered and returned to some other, more 'sensible' fold ... that what made sense up until now really didn't make much sense, but ... who knew?! And not only, "who knew?!" but also, when you got right down to it, who needed to know?
