I was taking a train to London’s Victoria Station. I had noticed that the carriage was noise and filled with people.
Before long, a train inspector comes to check out tickets. A passenger realized he couldn’t find his ticket but became quite upset. Then everyone in the carriage began searching the ticket, which was eventually found under a seat several rows from his owner. The person who found a ticket smiled with pleasure at his success.
No one in the carriage had previous spoken to or even noticed the ticket-owner before. Yet, they had so quickly offered the strangers their help. If we could show concern to others on need, the world would be a better place to live in.
