As a JW, I was only ever once in a position (that I recall) with a d'fed person. I was at the KH, and the d'fed was sitting at back (naughty step, lol) and after the Meeting (it was the Memorial) I made a point of going to speak to them (despite glowering looks from the Elders). I never did, or would, shun. It's unnatural, and I think it says a lot about a person who can actually do such a thing...currently I have only one JW who shuns me (long story - maybe I'll post it one day), at first I felt angry, now I just feel he's a total n*b and makes himself look an idiot.
looloo, I PMd you last week
