The mystery man who bought my daughter a cup

My wife went to pay for a new cup for my daughter and realised she'd left her wallet in the car. She asked the cashier to hold the item and said she'd be back in three minutes. As she walked away from the checkout she smiled at another customer, a man in his seventies, who smiled back, a "friendly and warm smile", she said.

She came back to pay and was told the man had already settled the bill. He'd left the shop. No message passed, and no waiting for acknowledgement. No thank you required or received.

What struck me was not the cup. It was the chain of events around it. How my wife felt in the moment. How my daughter probably felt, because of how her mother was feeling. How I felt, hours later, hearing about it second-hand.

What his motivation was, we will never know. What we know is that a small act, from a man who took nothing back, changed how an entire family felt for the rest of the day.
