I used to believe that I was an alien (from another world) when I was a child.
I thought my assignment was to take notes, photograph, and sketch my findings on this planet, like a field researcher in human skin. Then, one day I would be picked up and I'll have to give a presentation, like a show and tell. I wonder if this is a shared childhood memory.
I recall this sometimes when I'm feeling down and helps me in a way, it makes feeling like I don't belong a little easier and gives me motivation to come up with a fun new way to present my findings.
