A childhood belief about thunder and lightning

others believed things like this
- Thunders are created because of the collision of cloudsAnon
- I used to believe that where the sun peeks out from the clouds was where heaven was found.— Emily
- I used to think that if you ate cat food you would die. I found out it wasn't true
— Bob#4 - I used to believe that a vitamin was a small animal
only recently I have found out that it is not true... :)— Sylwia - I used to believe that when it would be raining the white clouds lost to the dark clouds.— janet
- I used to think that if you didn't put on your seatbelt, you WOULD crash.— Mer
