lol!
I think if I was stranded on a desert island with Mika, I would realise the situation, be a bit shy, not get my words out, stammer a bit, he'd think that I had a speech defect or was a tad retarded, treat me very kindly, and speak s-l-o-w-l-y, until I would gather up all my courage, tell him I'm perfectly fine, then have a panic attack because we're stranded on an island.
At this point, we would have a big arguement because he doesn't like fish, and neither do I, so one of us would be forced into going into the water, which I wouldn't mind, so I'd choose to go, leaving him to build shelter.
I'd return, soaking wet, and shivering, nothing in hand, and lie that I couldn't find anything, when really, there would be loads of fish, I'd just be too scared and grossed out to catch one. I would also use the shivering as an excuse to sit by the fire that he SHOULD have made by then, first, because I'm too afraid of making fire, even with a matchstick held at arms length.
Like I was saying, I'd sit by the fire, and force him to stand in the cold (it would be dark by now), until I felt a bit mean, and asked if he wanted to swap places, to which he'd most probably give me a very nasty mumble and shove me out the way.
That would result in me storming off to the shelter, and Hurrah! isn't it just great that after being washed up on an island, my iPod survives? (I love making up my own scenarios; everything turns out perfectly!). I would listen to Mika, and when he looks over my shoulder, he shall be happy, and whilst he is smiling because he know's deep down, I really DO like him, I would quickly push past and push lock him in the shelter using a big rock so that the fire was all mine.
