I was "actually" stranded on a desert island.

well... one part of it really, it is quite a large desert island.
i lived on this desert island for 24 years, accepted (but not totally) by a tribe of locals calling themselves Australians.
after learning their language, and some of their barbaric rituals, i started to plan my escape
this was made difficult by the worthlessness (in global terms) of the shells they traded as currency,and the geographic isolation of the island.
but never the less, i prevailed!

....only to find that i missed parts of the island.
