The Anger in Ernest and Ernestine by Leah Cherniak, Robert Morgan and Martha Ross. Ernest and Ernestine, very much in love, decide to move in together into a basement apartment with no windows and an erratic furnace.  Tension builds over where to place the tissue box and whether or not having sex on the kitchen table is hygienic.

We follow their relationship both cringeing and nodding in acknowledgement as their initial ideals of romantic perfection descend into homicidal fantasies.
