I heard from somebody who went to the Madrigal pub near Hampstead Heath with their family. They sat at a table while one of their party went to the bar to order drinks.
The person sitting at the next table realised they would be a stool short when they came back from the bar so passed a spare stool from their own table over without being asked.
These acts of everyday kindness are what make a difference; making a good day even better and a hard day just a touch less awful.
Even more stories of kindness:
