His name is Kim. Just Kim. We are introduced on the banks of the Saigon River in Vietnam. We are on a Viator excursion and he is our guide. He is polite, informative and the antithesis of a rah-rah guide who tries to impress with his clever dialogue so that at the end of the day he’ll get a bigger tip.

For Kim — and his eight customers — the end of the day was nine hours later.

It began with an hour-long ride up (down?) the river, to the Cu Chi Tunnels for a fascinating look at the underground network and weaponry the Viet Cong used in winning the Vietnam War, 40 years ago. Throughout the two hours or so we spent at what is now a huge tourist attraction, Kim’s knowledge and opinions made the tour better than expected.

The day also included a first-ever (and possibly last) visit to a cricket farm, which included a snack that was optional from the farm’s owners, and a lunch (long after we’d digested the little creatures) at an authentic Vietnamese restaurant. Not that you’d expect to find anything but authentic Vietnamese restaurants in Ho Chi Minh City, but this was so good we’ve been seeking the North American version ever since returning home.

Our day was nine hours and Kim’s has to be at least two more. When he told us he would become a father in a few months, our tip included a contribution for the daughter-to-be’s piggy bank — he said it would be her first deposit. As we parted, we exchanged email addresses, something we often do when meeting somebody so likeable and personable. We discovered there was more to him than Kim — Kim Nguyen Dinh — and we resolved to stay in touch.

Fast forward…

Our first email went unanswered for almost two weeks. These things happen. Sometimes they’re never answered. When Kim responded, he was apologetic. His father had been suffering from liver cancer for almost a year (long before we met him) and the prognosis was not good. His next email brought the inevitable news. In December, another email announcing the arrival of Cecilia, or Gia Kha Han in Vietnamese.

For his family, it completed the cycle of life.

When you exchange emails with strangers from a land far away, it’s not always like this. But when it is like this, you learn that we’re really not that different, are we?
