Rethinking

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!]
It is 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? The Love Song of J. Alfred Prufrock - T. S. Eliot 1917
