If you were lost on a small island with only one person,who would that person be?why?

要多少字?如果是短文的话,我先写一点吧.另外LZ是女生吧（我看资料的,所以我按照你是女生的写了）.
If I was lost on a small island with only one person,I will pick my knight in shining armor,someone I love.Ever since a young age,almost every little girl would have at least once thought of such man who will sweep her off her feet,rescuing her from the evil step mother or a giant dragon.By being stranded on a small island,I can say I would be the damsel in distress of my own fairytale story,and the brave man who is there with me will do all that he could to save both of us,and we will then live happily ever after.
Of course fairytales are still only fairytales.In reality,we will need food and shelter for survival.I would imagine on this small island,there would be trees and is surrounded by the ocean.In this case if we had just a small knife or a sharp item on us,we could easily make a spear out of it and use it to spear fish.Making fire would be our next problem.We all know friction causes heat,and so when you do it fast enough on something flammable,you may produce a fire.
In many ways producing this fire is hitting 2 birds with one stone.First of all,I am able to cook the fish we've caught earlier for food,and the smoke the fire produces may be used to attract helicopters and ferries near by like a rescue signal.
