I sniped 3 - 4 shots of these two guys; they didn't seem to mind - much. Five minutes later I saw in the corner of my eye the guy with glasses coming up to me, and I thought, now he's really going to tell me off for my respectless behavior. As I turned to him I realized that I not only knew the guy; I've known him for more than fifty years! Weird! (And we had a nice chat . . )
