The Love-Song of J. Alfred Prufrock by By T.S. Eliot

	Let us go then, you and I,
	When the evening is spread out against the sky
	Like a patient etherized upon a table;
	Let us go, through certain half-deserted streets,
	The muttering retreats
	Of restless nights in one-night cheap hotels
	And sawdust restaurants with oyster-shells:
	Streets that follow like a tedious argument
	Of insidious intent
	To lead you to an overwhelming question. . .
