ODIBF,
Hey man. So you have already gotten a bevy of advise. You handled it very well. Even when we fade, we still find ourselves emtionally subject to elders sometimes. Its kind of engrained in us. If most people asked you those questions you would jsut tell them to go to hell, but because it was elders, you feel obligated to entertain their questions, even if just for a minute.
Here is the thing to remember. You can always say no. Thats it. Can we come by? No thank you. Can you step back here with us? No I don't want to do that but thanks for thinking of me. Are you sinning? No, I'm fine...have to go now.
Treat them like you would any other person, and watch how your world opens up.
