When I called Martha, she laughed. “Oh, stop being so dramatic! He was fussy, and you looked exhausted. We’re at the park. We’ll be back when he’s hungry.”

I didn’t argue. I didn’t scream. I went back to the bedroom, packed a suitcase for myself and the baby, and waited. When she finally strolled back in two hours later, acting like she’d done me a favor, I met her at the door. I took my son, walked past her, and got into my car.
