Have you ever thought about how weird it is that hitchhikers sometimes stick their thumb out?
Not really, I have thought it was just the sign.
Only in the US/UK. I think different parts of the world have different signs for it.
Interesting.    I wonder if it has to do with being on the other side of the road.
Could be. I know that in Australia, they just point at the road. No clue what side they drive on though!
Kind of like the way water goes on the other side of the equator.
The Coriolis Effect! It's wild. Do you think that also has something to do with tides?
Maybe, or gravity
Tides are so bizarre to think about. Like, the fact that the sun and moon can exert a pull on water... it's crazy.
