When I was a kid I'd always have a ham and cheese sandwich for lunch but I didn't just need a specific ham, cheese, butter, and bread, I also needed to watch my dad make the sandwich in the order; buttered bread, ham, cheese, buttered bread, and then cut into four triangles. I also always needed the bread slices to be taken from the middle of the loaf with more imperfect sides on the inside of the sandwich.
in other news, my mum once said that I didn't really have many autistic traits growing up
