I was inspired to do this after seeing funny beliefs from people's childhood. The rules are simple: someone explains their (or someone else's) childhood belief(s), and people can comment on it and even rate how funny it is and/or say if they believed that when they were young.
I'll start for yall:
When my friend's younger sister was asked what she wanted to be when she grew up, she thought that meant she could be anything or anyone. For example, when asked she would say "A vegetable!" or "A pony!" One day, my friend's sister was in some sort of Doctor Who phase that she picked up after watching it. So in first grade, her teacher asked her what she wanted to be when she grew up. She awnsered (in the way she said it) "Kwara Oddballs!" And the teacher was so confused. She believed she could be anything until she was about 10 or so.
