Empty front row

I was giving a talk this evening at a nearby camera club.  This photo was taken while I was demonstrating how I use the flip out viewing screen on my compact camera to take candid photographs - which might explain the expressions on the audience's faces - they certainly weren't posing.

I don't know why no-one was sitting in the front row on this side of the room.  (There were a couple of people in the front row on the other side).  Perhaps they were scared of me!

I thought it was a slightly smaller turnout here than I have seen previously, but they share several members with my own club - none of whom was there tonight (probably because they've seen this talk before).
