Why do Mildred’s friends begin crying?

Montag proceeds to read a poem, Dover Beach, to the three uncomfortable women. When he is finished, Mrs. Phelps is crying, though she cannot explain why, and Mrs. Bowles is angry with Montag for bringing about trouble. All the women no longer know how to process genuine emotion. Mildred tries to calm the group, but the women are quite shaken and leave. Montag criticizes them as they go, telling them to think about the quality of their lives. Mildred goes to the bathroom to take some sleeping pills and Montag removes the radio from his ear as Faber begs him to stop, sure that he has gotten himself in trouble.
