I am a person of routine.
Or, I am a person who has routines. Whichever.
And, on top of that, I keep the lights off in the rooms I'm not in. Which means, when it's bedtime, I turn off the living room lights, walk through the dark kitchen and into the dark (until I switch the lights on) bathroom.
I've lived here long enough that I'm pretty decent with the spacing of my place and am generally able to make it to the hallway (via kitchen) by feel and the little bit of light that sneaks in the front door. I kind of look up and half sideways with my hands out until I hit the doorway and then I turn left.
Last night I forgot that I was airing out the dishwasher (letting the water dry up kind of thing?) and so it was open... which meant that when I walked through the dark kitchen towards the doorway I walked full force into the open dishwasher door.
Now I have lovely matching bruises on my shins!
