What am I supposed to say?
What I said to all of those dumb invitations is a very truthful answer.
Surprise, surprise--I haven't received one in years.
"When are you coming back?"
"NEVER EVER EVER."
"Oh, you say that now, but so many have returned to jehulu. They see what it's like in the world and realize we are in Thee End Times. You will too."
"I am so much happier now that I left, and so much healthier too. World events show life has gotten so much better over the millennia. I am absolutely certain I will never return. I have known this since the day I left. It is such a horrible, depressing way to live, with no future. I would rather kill myself."
This pretty much puts an end to the discussion.
This is what's right for me, in my situation.YMMV
