The weirdest ones to me were always the DFed people, one alone, or maybe two, a few seats apart, who would be sitting alone in the back row of every meeting.
Silent. Ignored. But desperate enough to be accepted that they'd accept a year or more of public humiliation.
(And if there were two DFed people, they'd both be ignoring each other, how screwed up is that?)
Firstly, what was it about them that would make them want to punish themselves like that?
And what was it about me and my family that we accepted that this human being could not be talked to?
At the end of the day, any of us that practised shunning were weirdos too.
