Signs...

...you're not firing on all cylinders:

You run an entire cycle of the dryer without actually transferring any clothes into it.

You make the boxed pasta side dish without the butter (or substandard vegan equivalent) when the directions only require you to add milk, water and butter. In case you were wondering, it is, in fact, edible without 1/3 of the ingredients. At least in my house.

You spray the shower with mildew cleaner than contains bleach and continue about the housecleaning as it soaks, forgetting later that you never actually cleaned said shower and instead, left the bleach there for your bare feet to step on and shower amongst, until they itched and burned and required you to huddle on the bathroom counter in your birthday suit as you frantically scrubbed them, lotion-ed them and socked-them. In case you were wondering, I still have a layer of flesh left today. Victory.

You go to the restroom and then can't remember five minutes later if you actually went to the restroom, and it never occurs to you to stop and evaluate if, in fact, you still need to go to the restroom. You just go again.

In a completely unrelated matter, my child seems to have found her thumb:

Remains to be seen if this proves to be a good or bad development.
