For instance: my sweet, kind Priest of Mara Altmer was walking along when he came by Salonia Carvain and her husband. I simply walked by Salonia and she said to me, "get away, Skyrim trash"
Another thing: people hate the Thalmor for talking about how you're interfering with their business when you are just walking by, well guess what folks, THE IMPERIALS ON THE ROAD DO THE SAME THING!
My point: humans are just as impolite and rude as Mer are, and not all Mer are rude, just like not all humans are rude.
