Oddly Impressed and Utterly Disappointed

How do you describe something that isn't even there? Something that has yet to be found. I can't feel it, I can't see it, I can't smell it. But it is there, in the back of my mind.

It. Is. There.

An action in need of an equal opposite reaction.
A title in need of a great storyline.
A fifteen years old girl in need of a purpose.

This is my diary, enjoy.
