Two Way Mirror

My earliest memory, comes from the age of 4. It was a birthday celebration, my Mother had organized a party, and all the children in my class were invited, and attended as well. I remember wondering to myself, how strange it was that she would invite strangers over to our house to celebrate my birth. Eventually, I would "know" many of these children, and interact with some of them throughout my future years of schooling. I couldn't explain to myself why they were at the house I lived at. I didn't know them, and they certainly didn't know me, actually none that attended the party ever would.
I remember asking my brother-in-law to put me on top of the roof of the shed in my parents backyard. The guests had no clue where I was, and weren't concerned with where I was(why would they be?).  However, I could see them, and I knew exactly where they were, and I continued to observe in confusion. I would continue this pattern to present time, the relationship with most of my peers is almost non-existent, no one is to blame. The  relationship is much like a two way mirror, I can see them, and their predictable behavior, but they can't see me, unless, I turn on the lights.
