Ding, I'd wondered that too. I would give a nice warm smile and a nod of the head to say hi. I think it was in protest to all those smug bastards at the back, so cold and judgmental. I think it was probably to try and subconsciously jolt them into realising that after all we are supposed to be Christians first and foremost. I'd hoped that they would notice that I had no problem with it, so why were they making a big deal about it, and why couldn't they show some warmth?
I'm convinced that the DF'd persons were so racked with guilt, that they probably had thrown up a kind of blind barrier, impervious to any communication. Now that I'm an inactive person, I'm getting the thousand yard stares too. Not had a greeting from a dub in maybe a year. Whenever I see a dub I stare at them to wait and see if there is a flicker of recognition. Nothing.
