It seems that several of us memorized the first lines of the Prologue to The Canterbury Tales at one point or another in our educational careers! I started writing down some of the bits and pieces of poetry that figure in some of my thinking on a regular basis, and discovered that I have a lot of first lines. I guess that Beatles songs are the only genre I've memorized in their entirety!
Take a guess, or add your own:
In the middle of my life I found myself in a dark wood . . .
Because I do not hope to turn again . . .
Hope is the thing with feathers . . .
After great pain a formal feeling comes . . .
You do not have to walk on your knees for a hundred miles through the desert, repenting . . .
There are more things in heaven and earth, Horatio, than are dreamt of in your philosophy . . .
Words, words, words . . .
A cold coming we had of it . . .
As kingfishers catch fire, dragonflies draw flame . . .
Those are pearls that were his eyes . . . (you can get credit for two here)
I will take a crowbar and pry out the broken pieces of God in me . . .
[Life] is a tale told by an idiot, full of sound and fury, signifying nothing . . .
