This is a most confusing, and therefore entertaining thread!!
First I read the original post, and thought "what the heck? Why and how would someone ride around with their little finger sticking straight out, as if holding a cup of tea when at tea with the queen"
Then I read some answers and thought that I'd landed on a different planet where everyone is suddenly holding their hands like that.
Then I read the question from Rising Glory about crossing the reins over, and frankly I'm completely baffled. People everywhere riding around with their little fingers stuck out, crossing their hands over each other?? Are you all mad!!
