Stuck,
I agree. I understand Talesin on this, but your'e correct in not faking it. I encouraged my children to show the Dubs, whenever they ran into them, to be positive and talk about the successful things they were doing. Avoiding the borgians (one was never baptized and the other wasn't DFed) or acting hurt/angry/aloof when around them sends the borg the message that you aren't happy because you don't have Jah and the borg. My daughter had a lot of justifiable angst towards the Borg but the Dubs she typically ran in to didn't know or have anything to do with the ugliness she experienced.
It is how I respond to all Dubs. I am kind, positive and if I get a chance to talk about my successes I do so. Even when they come to my door in the preaching work (and after 20 years I don't think most of them even associate my home with an ex-Dub), I am kind, thank them and simply tell them I'm not interested.
