As a small child I was absolutely convinced that people in the olden days lived their day to day lives in black and white, and that they walked slightly faster than we did today (assuming a frame rate thing?).
I’m gonna put this one down to my understanding of how TV worked as a ten year old. Everything before colour TV was black and white… therefore everything was black and white. Makes perfect sense.
What about you?
I believed it to be an absolute fact that all cats are female and all dogs are male. I had no idea how reproduction worked at this point, so it just made sense to me.
Then one day, a classmate was talking about her cat and how “HE” had done something funny. I had to clarify, “Your cat is a boy?!?” and my entire understanding of animals was shattered that day.
