We have all had the days when you fall out of bed mumbling "Wha'?" to yourselves, and peering out of half-shut, sleepy eyes in confusion. You wonder where the fluffy marshmallow man from your dream went, and why someone is banging at your door, shouting the time at you.

Or days when the energy you use to make your legs move has gone, meaning you slide down the stairs almost horizontally, picking up carpet burns and dust-bunnies on the way down.

Occassionally, there are days when your brain thinks too much about everything you don't want to think about, little devils sitting on your left shoulder muttering obscenities into your ear, sparking ideas. So you walk around muttering "No no no! Leave me alone!" and twitching your left shoulder madly. When that fails, you hit the shoulder, aiming to squash the little devils, but fail miserably, succeeding only in gaining looks of pity and fear from the normal people with lives at the post office.

That was my day.
