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?
Getting your official name changed to xxx “Middle Name” yyy as a joke…
Or have two middle names: yyy xxx. So, when you say your full name, you get to say "so good they named me twice. It’d be immense hassle as every form you fill out would get queried and passport control would pull you over.
