What is the funniest belief you had as a kid?

I had three:

1. I have quite a large family, and I asked all their ages. I thought that when I turned 43 I would literally BECOME my dad, when I was 62 I would become my grandmother. Slowly, I’d become every one of my family members until I died looking like my great grandmother.

2. That everyone had to have a different favourite colour, when someone had the same colour as me, I HAD to change mine. When the teacher asked everyone what their fave colour was, and all the other colours were taken, I said that the colours were all taken. 

3. I was unwrapping a new lego and building. I picked up the bag to throw it away, then I saw the sign that said “keep away from children” and “not suitable for children under three”. I was only four years old and immediately threw the bag in the furthest corner of the room and bolted out, refusing to go in until someone threw it away. I thought that you needed to keep it away from little kids cuz it would bite me or something.
