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 inthe carriage began searching the ticket, which was eventually found under aseat 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 noticedthe ticket-owner before. Yet, they had so quickly offered the strangers theirhelp. If we could show concern to others on need, the world would be a better place to live in.
