Twice in one month (!)
December last year. En route to NZ for Christmas/ New Year Hol with T+S. Stopped off in HK for a few days, and walking along the board walk watching the laser show, I saw an old buddy from years previous (Pusser's Grey, 1990ish). Despite shouting "oi, FLOBS", he failed to notice me in the crowd, so I figured I had missed a serious beer and anecdotes session.
Fast forward a couple of weeks. Sitting in the waiting area/ bar for the Milford Sound cruise (don't I know living?), who should wander in but same old self-loading baggage. Sadly, we were not embarking on the same fun-ferry, so another onslaught on the liver was narrowly averted.
And by the way, it turned out he had joined up with my wife's brother back in 1986.
