Michael carefully turned over and then sat up from the bed. That night, the weather was gloomy with no moonlight, making it pitch black outside, so the bedroom was shrouded in darkness.
Perhaps Michael could only make out the vague outlines of objects in the room, unable to see Betty's detailed expressions. At this time, Michael didn't notice that Betty wasn't asleep at all.
Her occasionally furrowed brow and twitching nose were giveaways, but since I was using a night vision camera, I could see what Michael, lacking night vision, couldn't.
Michael seemed to have gotten used to the perks of being with Betty and thought he had her sleep patterns down pat. Overconfident, he was too careless as a youngster, failing to listen closely to Betty's breathing.
From the video, I could tell that Betty's chest was rising and falling unevenly, but Michael, in his haste, overlooked this detail.
