When I was five, there was a neighbor's tree that was perfect for climbing into and hiding. Often, I would go up there with a book and sit for who knows how long. Once, I remember the neighbor trying to see if her senses were right — was there a little human up there — but the thickness of the branches seemed to hide me.
This is one of my earliest memories of non-human entities feeling like kin to me.
Of course, as I grew older, society did its best to dampen my connection to the other beings who inhabit this world. I forgot for a time that I am connected to all things and can understand them on a more subtle level.
