“Ain't all buttons and charts, little albatross. Know what the first rule of flying is? Well I s'pose you do, since you already know what I'm 'bout to say.

I do. But I like to hear you say it.

Love. Can know all the math in the 'verse but take a boat in the air that you don't love? She'll shake you off just as sure as a turn in the worlds. Love keeps her in the air when she oughta fall down...tell you she's hurtin' 'fore she keens...makes her a home.”
― Joss Whedon
