He's been a real brick.
Although I suspect he has some standard letters adapted to our standard questions (e.g. misgivings about leaving the org, wondering about the existence of God, the supposed 2 class Christianity, whatever), it's very kind of him to take the time to reply to us at all, given his frailties (he had a stroke a couple of years ago - no paralysis, but it left him with low energy), and he does generally personalize them.
He's a good man.
