I wish I could say the right words
To lead you through this land
Wish I could play the father
And take you by the hand
Wish I could stay
But now I understand
I'm standing in the way
Giles, the song "Standing" in the musical episode of Buffy the Vampire Slayer
You see this little hole? This moth's just about to emerge. It's in there right now, struggling. It's digging its way through the thick hide of the cocoon. Now, I could help it - take my knife, gently widen the opening, and the moth would be free - but it would be too weak to survive. Struggle is nature's way of strengthening it. Now this is the second time you've asked me for your drugs back... ask me again, and it's yours.
