I’ve literally just had a chat with a very frail old man about steam engines. I almost walked by as I wasn’t sure he would want to talk but he caught my eye and we started chatting about his magazine. It had a picture of a steam engine on it. He started telling me about working as a water boy on a farm and how he used to fill the engines up. They had four steam engines to look after. It was only a moment but his eyes lit up. Seeing him remembering with fondness a happy time in his past, made me happy sharing it with him.
