He knew it was the only way out
The doctors told me I would be placed on a seventy-two hour hold for observation. Knowing this was the only way out, I obeyed and diligently signed all the papers. I hated my parents but still felt the inescapable drive to prove to them that I was worth something. I had to show them I wasn't crazy. As the hours passed, I was shown to a blank room with plastic sheets and plastic pillows, which caused me to wonder what kind of distant confused souls had been imprisoned in this sterile place. There were bars on the windows and the only door out of the unit was locked 24/7. I knew my only refuge for the time being would be through the hour a day art therapy class and the smoke breaks I could take at will. They had given me a legal pad after my parents had told them of my affinity for writing. With it I set to work on the flow of words and the river of thoughts, both dark and hopeful that careened through my tired mind. Instead of sleep, I would write. I expressed my vicious frustration for the place and thought constantly of the passing hours, counting them down as they went. Because of this I was thankful for the eight to ten I would use up easily in my escapes to the world behind my eyelids. There I was free and could experience a life unhindered by limitations of ethics or gravity. When I'd awake I'd write what I could remember of my escapes on the obtrusive legal pad. I had the suspicion that the attendants would come in and read my thoughts as I was eating meals or watching TV and I wondered if this was hindering my ability to get out. I wondered what kind of opinions and judgments they were forming about me. I had bared my soul on those pages explaining desperately how the thoughts would not leave even in this place, where it mattered most that they were gone. The fuckers would never leave. Maybe I was crazy.
