Here's the thing.

I know that the lightbulb is burnt out on the basement stairs, yet each time I open the door to go down it plays out like this in my head:

*click*

Why didn't the light go on?

*click click*

Oh right, we need a new lightbulb. I keep forgetting.

Eventually the Man will say 'Honey, do we have any lightbulbs??' enough times that one of us will do something about it, but until that happens I've decided to make peace with it.
