Handwriting as an indicator of mood

I've been signing some correspondence this morning at work. There's a certain way I usually do it.

Today I can't do it right at all.

My handwriting is too loose, too uncontrolled, too big, too curly. I try to get tight scribbles and instead end up with big loops. And they're not even real loops, they're more like shapeless curves. Big shapeless curves.
