"May Day" by Alex Colville
It started out innocently enough. She found a couple of empty creamers and a pair of panties in the glove box of his VW Bug. But, not long after that, for various reasons (none of them convincing), he started coming home late, with his shirt inside out and reeking of two percent. The almond milk stain (perhaps she was lactose intolerant?) on the back seat of his car was the last straw. She confronted him. He denied it (of course). Clearly it was over, more for him than for her. Bang, bang, shoot, shoot.
