A quote from Rei Ayanami:

"Will Life ever stop playing games with my courage? My coldness upsets many, but it is my only security. How fragile is my heart if I am to face the world alone? Thousands of smiles won't brighen the mood that is forlorn. How doubtful the faces of others, when I see glimpses of fading lies in their eye? How much I wish to trust freely, like a silver boat on the wide ocean glides. How naive my mind is to believe."
