Seriously, if I only had two minutes with a "still-in" family member or JW friend, THE LAST THING I WOULD WANT TO TALK ABOUT WOULD BE THEIR RELIGION!
I would simply want to know how they are and to let them know I miss them and they are always welcome to keep in touch. Their response to that (which so far has universally and without exception to be to avoid me) would determine if and how I would ever discuss religion with them.
