All kinds of things give one pause suddenly. I often notice a moment when my attention suddenly fastens enquiringly on the one who has said so little during what was otherwise an animated exchange. And the gesture you made itself is so potent, as if to say, "see, as different as we may seem, at the core is..." see what I mean? You describe a moment between two people that would seem poignant I think, to anyone.

Or, sure, it could have been a homoerotic "moment" and later be construed to have been the seed of his undoing...but I don't think so.
