You are alone on a desert island. Or are you?
Something bad happened, your ship sank or your plane crashed, and you find yourself as a sole survivor on a deserted island.
All goes well, you are there some months now, and you have your life on track.
You build yourself some shelter, eat food from the trees and the ocean, and you befriended the, presumed extinct, Dodo.
Then, while wandering around one day, through the bushes you spot another human!
What do you do?
Make yourself known? Or not, and stay alone?
Would it influence your actions if he/she was of the same sex?
