It was a winter morning, just a couple of weeks before Christmas 2011. While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival, he parked his bike outside the back door as he usually does. After working for ten hours, he returned to find his bike gone. The bike, a black Kona l8 speed, was our only transport. Trevor used it to get to work, putting in 60-hour weeks lo support his young family. And the bike was also used to get groceries(食品雜貨)．saving us from having to walk long distances from where we live.1 was so sad that someone would steal our bike that l wrote to the newspaper and told them our story.

    Shortly after that, several people in our area offered to help. One wonderful stranger even bought a bike, then called my husband to pick it up. Once again my husband had a way to get to and from his job. It's really fantastic that a complete stranger would offer help to someone they have never met before. People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience has had a great effect in our lives. And we believe that no matter how big or how small, an act of kindness shows that someone cares. And the results can be everlasting.
