You say grace before meals.
But I say grace before the play and the opera,
And grace before the concert and the pantomime,
And grace before I open a book,
And grace before sketching, painting,
Swimming, fencing, boxing, walking, playing, dancing;
And grace before I dip the pen in the ink.
by G.K. Chesterton
