      It was a winter morning, just a couple of weeks before Christmas 2005. 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 putting in 10 hours of

labor, he returned to find his bike gone.

      The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour

weeks to support his young family. And the bike was also used to get groceries (食品杂货), saving us from

having to walk along long distances from where we live.

      I was so sad that someone would steal our bike that I 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 really is an

honor that a complete stranger would go out of their way for 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 spreading effect in our lives because it strengthened our faith in

humanity (人性) as a whole. And it has influenced us to be more mindful of ways we, too, can share with

others. No matter how big or how small, an act of kindness shows that someone cares. And the results can

be everlasting.
