Ok so all you have to do to rp is create a character and put them in the story please do not make them perfect or pure losers make them have depth and good personalities ohh and no one sentence posts please do at least one paragraph. The rp begins right when the cast away people awaken on the island. I'll start

As I awaken I fell the warmth of the sand and the glare of the sun in my face. I then realize my arm has the moist greasy feeling of blood on it leaking from a giant scar running up the length of it. Then I grab the rock beside me to get up and take a view of myself. I see I have been beaten around on the fragments of the boa as I have bruises cuts and blood dotted around my body. As look over the water I see a bloody shallow of water around me. I then realize my family is nowhere around me. Then I become hit with the truth that my family was killed I then become a wet soggy mess of blood and tears. Suddenly I realize I must man up if I am going to live and find myself clearing my emotions I then begin the hunt for survivors because even though I am young I know what to do during these situations because of my reading.
