Ah! But a violent emotion could also be someone freaking out with joy, jumping and leaping about, screaming at the top of their lungs, couldn't it?
I could definitely injure somebody in the state I'm in right now! :-)
OK, OK... I've only ever seen the word "conniption" used in a negative sense. Never thought of a conniption of happiness before!
Please don't injure anyone, Ruthy! ;)
