“The Love-song of J. Alfred Prufrock”  is the inner monologue of one man, Prufrock as he debates how he will act at the implied social event he is planning.  Throughout the poem, there are two major symbols of types of people who find themselves lost without a real ability to effectively, or more to the point, with any purpose communicate with the party-goers around them.  First is Prufrock with his literal inability to say anything at all.  He is completely and utterly unable to communicate with the world around him. Absolutely anything he says will result in the woman saying

That is not what I meant at all./That is not it, at all

The reader also gets the sense that Prufrock simply believes that he does not at all belong in the place where he is.  We see again a sense of the individual feeling that they are the disturbance of the world around them.

Do I dare
Disturb the universe?

The next piece that we see is the women. 

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

I think it would be extremely interesting to get into the minds of the jabbering women. I have a hunch that they would be wishing that they could say something of purpose, seeing no reason to their lives other that to speak of nothing.

These characters are a much more realistic presentation of a character, and encompass the piece of modernism of presenting and inner psychological reality, here, the reality of a lack of communicating ability.
