I have learned from Grey's Anatomy the following things:
A heart can breathe on it's own without the body cavity surrounding it.
You can survive Stage 4 Metastatic Melanoma in your brain.
Everything can change in an hour.
If you want crappy things to stop happening to you, then stop accepting crap and demand something more. (Christina Yang said that, obviously.)
And no matter if you have heart and spirit like Bambi, you give it your all and decide that you're sticking to your guns, fighting and staying true to your heart,
you can still get hit by a motherfucking bus.
