Biscuita and Gravy

She and he sat eating lunch, biscuits and gravy, at the table in the small kitchen of their studio apartment.  She read the newspaper as she ate.  She looked up.  "My God," she said, "this mother and father murdered their sixteen-year-old daughter . . !"
"Some people are garbage," he said.
". . . they wanted her to marry some rich guy, but she wouldn't because she was in love with some poor guy . . . they said they killed her for family honor."
"Those people with that family 'honor' buisness are like primitives who've accidently blundered into the 21st century -- the civilized world -- from the Stone Age."
"We need to do some demonstrations against them," she said.
"Have to take off from work for that," he mumbled.  "Less gravy."
"And the price of flour is going up," she said.  "Less biscuits -- and gas is going up another nickel . . ."
"Less gravy means less marriage, less flour, less biscuits, less gas -- gravy affects everything . . ."
" 'Gravy affects every --' what kinda gravy you talking about?"
