Grey's Anatomy, Season 1

Meredith:
[voiceover] Secrets can't hide in science. Medicine has a way of exposing the lies. Within the walls of the hospital, the truth is stripped bare. How we keep our secrets outside the hospital – well, that’s a little different. One thing is certain, whatever it is we're trying to hide; we're never ready for that moment when the truth gets naked. That's the problem with secrets – like misery, they love company. They pile up and up until they take over everything, until you don't have room for anything else, until you're so full of secrets you feel like you're going to burst.
