Thinking about sam

I have been thinking about Sam a lot, since being here in Switzerland.  We used to be great childhood friends but no longer are talking because of adult things (bad, ugly family stuff). I last saw him in NYC in September 2007 when I was going through my divorce and he was working in a corporate law firm. He told me after our dinner together, that we could never be friends again. That was 8 years ago.  

I met him when I was seven and we rode bikes around as kids, played hang-man after dinner and watched re-runs of Three's a Company. When we were in our 20s we lived together for a summer and traveled together in Africa together for 5 weeks. 

After his senior year in high school he lived in Switzerland for a year. I remember that when he came back he seemed so different. So happy and motivated and smart. He lived with a Swiss family who were very active skiers and hikers. I imagine he is still very much in touch with them and I just wonder - now that I am here in Switzerland, in the Swiss German region - who is this Swiss family? Will I ever run into Sam here?
