Trust

Trust: The reliance on the integrity, strength, ability, surety, etc., of a person or thing; confidence.

Trust is a tricky thing. It is earned, not given. Those which we choose to place this honor upon may deserve it. But sometimes, we grant someone trust in full confidence that they are worthy, only to be shown they were not. How do we know who is worthy and who we should avoid?
It amazes me how easily you can be wrong. There's people you think you can let into your world, your heart, your thoughts, your body. But once they get there, they play their own game. They ninja your brain into thinking they deserve the responsibility, only to use it to their utmost advantage or entertainment when the right moment presents itself.
The sad result of this being, eventually you learn to trust absolutely no one. It seems to be the only logical way to avoid letting others hurt you continuously and continuously. Its a way of life, and a hard one. And it fucking sucks.
