Yep.
I'm self-diagnosed.
But I'm just sure I have "Adult-Onset Attention Deficit Disorder".

What else can it be?

I start the washer to run a load.
While the detergent is getting all friendly with the water, I set off to get the hamper.
On my way, I'm called by my child to answer a question about schoolwork.
Or my husband needs something and doesn't know it's location.
Then I see something out of place and pick it up and put it in it's rightful location.
I stop to make my bed.
I pull something out of the freezer for dinner.
I Google a new recipe idea.
I...

....forget the washer.
It has run through all the cycles and is now clean.
Laundry still needs to be done but my washer is clean.
