It's not the first time on this trip that we've run into people we just met. We sat beside a couple from Philadelphia on the train from Oban and ran into them again near Ben Nevis. And there are others.
Traveling is like that. You meet people you think you'll never see again — and then bump into them the very next day. Fellow travelers can make all the difference.
A P.S. to this post: we met our Belgian friends again the very next day.
