The soft glow of the laptop screen illuminated John’s face as he watched his wife, Emily, practicing Mandarin. He knew what she was doing. He knew the reason. She didn’t know he was watching. He felt a deep sense of… bewilderment.

He got up quietly and left the room. The house felt too big, the silence too loud. He went outside, the cold air stinging his face. He walked around the block, the feeling of the pavement under his feet offering a small grounding sensation.

He returned, the house still quiet.
