I used to think grown-ups could see what kids were thinking because kids' foreheads acted like mini tv screens, which showed whatever the kid was thinking. This was confirmed when my mom was excited about me getting my bangs cut off. I thought the adults just all knew never speak about this ability, and I made sure to think nice thoughts when adults were around. I couldn't wait to grow up.
