Living Alone by H. Donald Cabinet

Agoraphobia it's not, but I can hardly bear the din of others while I wait at the station. I sit. And wait. The girl with overbitten teeth says, "I'm always so excited to have the day to myself, and, then, by 5 o'clock, I'm like, 'I'm sad.'" Jealous when she says on the phone (to Carrie?) that her destination is Chicago.
