So big difference in my birth family than the BoB and website one. My home was LITERALLY Flatland, just later than the book. (A Square was history to me; You might see some similarities to a famous fanfiction too.) But my birth family was a line and an isosceles triangle of lower class. Workmen class. I don't know much about them. My adoptive family was merchant class, a line, another equilateral triangle, and an irregular triangle (Liam).
But the tradition of moving an equilateral to a new family didn't stop years ago. Which sucked. I wonder what my life would have been like with my birth family--probably stuck very poor. The only one of my adoptive family I really cared for was my brother, and I lost him at eight-years-old. I ran away at 15. And a sphere (Z sphere) found me.
Z sphere continued to raise me, and was probably more of a parent than anyone was to me. I appreciated him, but the damage was done to my mind before that. Trauma had set in.So while I was happy in the 3rd dimension, I was plotting.
So when I went back, I tried to get people to follow me and see what they were missing. But it ended badly.
