Sadly, I've been suffering from grumpiness since I was about 3. Fifty odd years later, I would have had it down to a fine art without any help, thanks cancer, you %#!*er.
It would be difficult to construct a scale to measure grumpiness, but if such a thing existed I would be an Olympic grade grouch. My rad burns are conspiring with my recently imposed menopause, the Femara, lingering chemo crappiness and impending penury to make me, quite possibly, the surliest human in the Southern hemisphere.
