Resi,
Your post really brings to light how conditional and insincere the Jehovah's Witnesses are. When they first show up at your door step they behave like your long lost cousin specially if you accept the literature. And if you actually accept a study right then and there, wow, you are literally that person's BFF. And if you ask to accompany them to a meeting then WOW they will literally kick their spouse, kids, and grandma out of the vehicle just to make sure there's space for you and you can attend.
It's insulting that true friendship is based on whether you agree with the anti scriptural teachings of their Organization.
My suggestion would be to emotionally end your relationship with them in every possible way. The thing is while you are reminiscing and dreaming of times past, these incredibly shallow, robotic, imbecilic, and misguided people have probably already acquired another person who has replaced you as their new BFF.
