I found this on my phone. Looking at the filenames in my recordings folder I see that I made just one other recording this night (April 29, 2016), but the two seconds of silence contained therein offer no clues. This recording has a lot more going on. I’m not sure what, but it sounds like Sarah saying “high-pitched” and then me swallowing the phone and belching as peristalsis runs its course.
You’ve been warned:
