If Goneril Had Had a Brother

The kids (son, daughter) were wrestling yesterday when son begins to cry loudly. Daughter exits the room and comes to sit with us. She shrugs. "What happened?" we ask. "We were just wrestling, and then he started to cry and cry," she said. "She STOOD on my HEAD and it HURT!" shouted son. "Aaaand I did that," she said. "By accident."
