Thanks so much for your comments, Arthur. I'm so glad you mentioned "confusion" as a source of annoyance. When I think of confusion, I think of all the poor signage I've experienced at airports in particular. Very annoying. And great point that there is often an underlying fear under annoyance (and under lots of things that make us angry), and that the key is to find a humane way to adapt--perhaps "tend and befriend" as opposed to "fight or flight." Thanks again for your insights!
