From a reader:

“I understand your reluctance to admit to doing your best writing in the bedroom. All of my best writing actually occurs—this is completely serious –in the bathroom. It started in high school when I was working on an essay short on a deadline. I had a situation which kept me making frequent trips to the restroom and eventually just took my notebook and pen with me. The result was I completed the paper quickly and didn’t leave the bathroom until it was done. Now, I keep a journal of thoughts and short essays in my bathroom (I never allude to the location of the writing in the actual writings) and have written some of my best [work] in that notebook.

“Thanks for writing [your] book about Reagan, regardless of the location.”
