Sometimes I do. In hindsight, I think it would have been cool to pull off a successful fade as that's what the Depends-wearers in brooklyn seem to hate the most, that is, people walking away and not looking back. I could have done it too - my circumstances were such at the time that the elders would have had a very difficult time tracking me down.
When you DA, you're still defining yourself in relationship to them, still actively participating in their vast labeling system that they use to categorize every person that has ever had any sort of tie to JWism.
Otoh, if I had faded, then I would have always felt so awkward when I saw former JW acquaintances out in public or at work or whatever - 'do i say hi? should I approach them or make eye contact? what will i say if they approach me? do they know that I'm faded?' Those sorts of tricky social situations are very taxing for me, and by DA'ing I was able to circumvent all that.
