It's really all about circumstances. We chose to fade because of family and business contacts that needed to be kept intact. If we were DF'd or DA'd, some of these people would feel they couldn't talk to us or, if they did talk to us, they'd feel guilty about it. The way things are now, we are largely ignored/snubbed'shunned to various degrees, but some dubs feel they can talk to us and they do.
Just today, a guy I work with (another department and our paths don't cross much) ran into me between buildings and said, "I haven't seen you in a long time. What congregation are you in now?" We were in the same congo before we told everyone we were changing halls and moving to another one, after which we essentially disappeared.
I told him we had moved to that congo but that we hadn't been to very many meetings there and that we weren't going anywhere right now. It just felt like the right thing to say. I wasn't sure how he'd react. He said, "I'm not getting to as many meetings as I should, either. I'm just hanging on by a thread." He started to tell me why and it looked like a really interesting conversation was about to take place, but then his boss walked by and start asking him a bunch of questions about some project they were working on so I excused myself.
My point is, he felt free to talk to me. That may turn out to be a good thing, for his sake. We'll see.
