Oh boy, if that’s what it is, then this is just an ordinary night. You and I are going to go home and go to sleep and tomorrow when we get up that sun’s gonna shine. Just like yesterday. Good ol’ yesterday.”
—Theodore Simonson. Irvin S. Yeaworth, Jr.. Steve Andrews (Steven McQueen)

Or if you insist, as you have a right,
On spreading your wings for a loftier flight,
The moral is—Take care how you light.”
