The old piano keys were yellowed, and some didn't work. Mary was running her fingers across the keys, attempting to play a tune she remembered from her youth. She messaged, "Do you remember the music?" to a contact she knew as "Jim from work". It was actually Jim's ex-wife.

The ex-wife replied, “I remember everything. How’s work?” Mary felt a sudden flush of embarrassment. She stared at the message and felt the sting of regret. She switched off the piano and walked away.
