Sorry, but I'm a human being. That means that I sometimes get annoyed. But, by being annoyed at things you work to make them better. For example - I've always called for better health education. And if you expect me to not be upset by someone insulting me for no reason except that they didn't like what the nurse told them, then you must be some Buddhist Master... How about when I get punched by a drunk - should I stand there and take it, after all it makes the 'patient' feels better
