I am like you too - I never get angry BUT I disagree about it never being useful. Anger can act as a signal to someone else, a social cue, that what they are doing is wrong and not acceptable. When my children were younger, I used to sometimes #pretend# to be angry when they did something naughty because I did see a useful function in this. Of course, being a complete softie, I loved every single thing they ever did or said....had they known this, it would not have been helpful for them! I do wish that sometimes I would be angry for real as I imagine that other people pick up on this emotion and modify their behaviour accordingly. I have never been angry with my husband and now he has a slight superiority complex!
