My favorite.
Pangur, white Pangur,
How happy we are
Alone together, Scholar and cat.
Each has his own work to do daily;
For you it is hunting, for me, study.
Your shining eye watches the wall;
My feeble eye is fixed on a book.
You rejoice when your claws entrap a mouse;
I rejoice when my mind fathoms a problem.
Pleased with his own art
Neither hinders the other;
Thus we live ever
Without tedium and envy.
Pangur, white Pangur,
How happy we are,
Alone together, Scholar and cat.
Samuel Barber; w/ anonymous Irish poem of antiquity
