One thursday I went to the meeting as usual, and by the time the next Sunday rolled around, I knew I would never consider myself a JW again. I never went back to the hall. I did however go to the memorial held at a school auditorium that year (can't remember why? Maybe to see everyone? Keep a facade? ...can't remember).
Anyway, I approached that situation, and the numerous times I'd meet people in restaurants etc, by being magnanamous, big smile, etc. Anything but the whipped spiritually weak non-meeting attender they want to see. This throws them off gaurd. And to all the "so good to see you again's", I replied with "good to see you again too!". I think they meant it probably, and I know I did.
I think the above approach tends to throw most witnesses off-gaurd, and they are less likely to give a "talk" about how much we need to be at the meetings and close to Jah's organization in these last days... but on the oth, the absolute best way to keep family is to play the "I'm just weak, bear with me, I know I'm not doing the right thing, but I just can't right now" card. Personally, I actually planned to do that in theory, but something about me just couldn't pull it off in practice. For one thing, it's a bit dishonest; not that there is anything wrong with being dishonest when you're at war with an evil empire.
