Wind's amazingly awesome and odd idea shop: idea #1: A day in the life of the diseased.
Diseased kids, diseases of which no one knows. There is no cure, nor has anyone heard of it. Throughout these diseased kids lifetime, they may or may not know any others like themselves, though they must find others like themselves. Whether it's coincidence or not they must seek each other out. It is not an entirely deadly disease unless they choose though themselves. Their goal, to meet one another and find a cure, but first they must understand the disease themselves.
Now to what the disease is. A disease that is believed to be which one would go into which would be much like a coma, but at times they just walk around normally, and then they collapse, and the time they would awaken is entirely unknown. Though their entire system is stopped, as though they were dead. Say you were fifteen years old and six years had passed while the disease was in affect. They may be twenty one, but would still only appear fifteen, as though everything in their life had come to a complete halt.
The reason for the disease? Unknown. The name for this disease? Unknown. How can you cure it? Unknown. Is it contagious? No. Many people have a better grasp about it than others, but the only way to truly overcome it, is with the help of those also diseased, and the help of those around them. Only then, can this disease cease to exist.
