This was tough to judge all of the entries were great but in my opinion yours did it the best also sort of bias since i agree more to your statements because if we took an example
Like japan look at everyone there they all stay on one side of the escalator to let other people walk up on the other lane another example if your in a train/subway in japan people dont sneeze chew gum talk using the phone everyone there is considerate to one another and look how they have become the worlds most advance countries anyway i vote for you good luck!
