I can vouch for the very real and troubling decision to hold back information from other people. Some experiences or portions of experiences are extremely personal. And let's face it, this genre is LOADED with redicule and labelling. I'd bet that if Penniston held back some deets, there may be one or two others involved that may have as well. It's perfectly understandble from where I'm standing do to so. Not all humans are experiencers, and the experiencers don't "owe" their stories and exeperiences to everyone IMO.
