Ive seen this thread before, cant remember if it was on here or somewhere else, but a lot of funny stuff was said so;
What is the dumbest thing you believed as a kid?
Personally i thought untill the age of about 11 that cats were baby dogs, and that my mum could change the volume of the radio with her mind, thanks to one of those volume dials on the steering wheel.
I remember reading about someone whose brother told him the electrical transformer at the bottom of his garden was a space ship his parents were slowly charging to send him back to his home planet, and when he reached 12 he would finally make this grand voyage.
Another one that happened as an adult was managing to convince my friend whilst staying in a rat infested hostel that the rats were just "ground squirrels", i think she believes it to this day
anyway, what are the dumb things you thought as a kid?
