She ignored Joe and hit Richard twice more, once on the left side, once on the right. There was no satisfaction in it other than the sound, the meaty slap of her palm against his ear and cheek, the cheek she’d cupped, the ear into which she’d whispered I love you and deeper and the names of their daughters, just after they were born. “You bastard!” she cried, and let her hands drop to her sides.
