- When I was little I thought everybody was a Christian, (I was raised like that) so once I said to classmate when I was a kid: well God made us right?
And he was like: No, you don't know that. And I was completely dumfounded! D: When I discovered internet I found out how and what and then I went atheist later.
- Why do metal stairs with holes in them exist?
I found out later it's because eventual rainwater could go through the holes and make the stairs less slippery
- As a kid I thought traffic lights where controlled by people underground in rooms or something, and I always pressed the button.
Later I found out you don't have to press the button because sensors on the road detect everything. Still don't know why buttons are there.
