Which lines from “the love song of j. alfred prufrock” best express themes of alienation and isolation? and i have known the arms already, known them all— arms that are braceleted and white and bare but as if a magic lantern threw the nerves in patterns on a screen:   would it have been worth while no! i am not prince hamlet, nor was meant to be;   am an attendant lord… i have heard the mermaids singing, each to each. i do not think they will sing to me.
