"While I would love to find a poetic way into this", writes Sarah Dunant, "I think it best just to spit it out. I'm angry. And I have been angry for quite a while now".

Sarah says she doesn't see herself as an angry person - but wonders why aggression and outrage seem to have become so much part of our emotional diet.

She proposes some solutions - including an National Anger Day - a great moment of catharsis to help us all be a little less....angry!
