I imagined that I would open mind doors when I was around twelve years old, and I imagined that marking a thought, bookmarking it in my head could allow the older me to go back whenever it was possible. I drew about this in my philo class one day, and it looke like floating doors in blackness and me opening up to another me; they were acquainted but were still timidly trying to understand one another. The younger would usually shout "hello!" first because the older was usually trapped in some sort of emo dilemma or would be entangled in a web of adult complexities.

I think I'll give it a try one of these days.
