T.S Eliot - The Long Song of J. Alfred Prufrock (selection)

In the room the women come and go        35
Talking of Michelangelo.

And indeed there will be time
To wonder, “Do I dare?” and, “Do I dare?”
Time to turn back and descend the stair,
With a bald spot in the middle of my hair—        40
(They will say: “How his hair is growing thin!”)
My morning coat, my collar mounting firmly to the chin,
My necktie rich and modest, but asserted by a simple pin—
(They will say: “But how his arms and legs are thin!”)
Do I dare        45
Disturb the universe?
In a minute there is time
For decisions and revisions which a minute will reverse.

For I have known them all already, known them all:
Have known the evenings, mornings, afternoons,        50
I have measured out my life with coffee spoons;
I know the voices dying with a dying fall
Beneath the music from a farther room.
  So how should I presume?

And I have known the eyes already, known them all—        55
The eyes that fix you in a formulated phrase,
And when I am formulated, sprawling on a pin,
When I am pinned and wriggling on the wall,
Then how should I begin
To spit out all the butt-ends of my days and ways?        60
  And how should I presume?

And I have known the arms already, known them all—
Arms that are braceleted and white and bare
(But in the lamplight, downed with light brown hair!)
Is it perfume from a dress        65
That makes me so digress?
Arms that lie along a table, or wrap about a shawl.
  And should I then presume?
 And how should I begin?
