Kit is a middle-aged former hippie living with her husband, Rafe, and their three children. Rafe and Kit met at an anti-war protest two decades ago. In their middle age, they became more conservative and grew to hate each other. Kit couldn’t stand how Rafe was so obsessed with model rockets to the point that he spent all of his time building them. She found his sexual advances weird and unwarranted. When he mailed her a divorce out of nowhere, Kit was further angered. It turns out that Rafe had been cheating on her for more than a year. Despite having sent her the divorce by mail, he keeps living with her. He purchased a separate home elsewhere, to which he would move later. Her anger at the divorce makes Kit comically pro-war; she begins to see why people imagined that nuclear weapons were necessary. Before the divorce summons had come, Rafe and Kit had planned to go on vacation to the Caribbean with the kids. Although Rafe suggests that Kit shouldn’t come, Kit insists. They pass an awkward vacation together, everyone sleeping in separate beds. The twins don’t seem to mind, but the couple’s eldest son, Sam, seems distant. Kit has a horrible time. When they come back to their suburban home, Kit imagines telling everyone that their marriage didn’t end with so much as a fizzle than an explosion. Despite the fantasies she dreams up, she soon realizes that the time she spent in love with Rafe is so unfamiliar that she can barely remember it anymore.
