I very rarely came across rude or disrespectful people. I don't know how I slipped by all of them but I honestly can't think of one experience off the top of my head that was like that. I'm sure they're there but I'd have to think really hard to recall them.
Remember, if the time should come when you have to make a choice between what is right and what is easy, remember what happened to a boy who was good, and kind, and brave, because he strayed across the path of Lord Voldemort. Remember Cedric Diggory
