What to say to Grandma?

[cosmowanderer]

Update... she emailed me again, asking if I've changed my mind about being an atheist. I told her it's not really something I can just change my mind about, but if she would like to ask me any questions about it, she is more than welcome to. She replied saying she has no questions but that she wants me to change my mind before it's too late. Feeling a little pissed off, I replied letting her know that I have an open mind and that if I ever do find reason to believe again, I will, but that I've searched for god more than most people and have left no stone unturned or question unasked. I told her I feel atheism isn't an "option" I just whimsically chose, but the conclusion to an extensive decade-long search.
