When I was a missionary, it was fairly unsettling to realize just how much information about people and their daily routines was contained in the area book app. I shudder to think about the contributions I dutifully made to that database while I served.
On the other hand, I am pretty curious to see what they wrote about me now that I'm an ex member who's had a couple interactions with missionaries.
"We don't do infant baptisms because we believe that people should have the agency to make such an eternally-important decision on their own.
"... Anyway, want to come to little Timmy's baptism? He just turned 8 years old and has decided to promise that he will commit the entire rest of his life to the Church! I'm so glad he's finally old enough to make that choice on his own!"
