This is how it manifests:

I decide to water my garden.  As I turn on the hose in the driveway, I look
over at my dirty ol' pontiac and

decide it needs washing.  As I start toward the garage, I notice that there
is mail on the porch table

that I brought up from the mailbox earlier.  I decide to go through the mail
before I wash the car.

I lay the car keys down on the table, put the junk mail in the garbage can
under the table, and notice

 that the can is full.  So, I decide to put the bills back on the table and
take out the garbage first.

But then I think, since I'm going to be near the mailbox when I take out the
garbage anyway, I may

 as well pay the bills first.  I take my checkbook off the table, and see
that there is only one check left.

My extra checks are in my desk in the study, so I go inside the house to my
desk where I find the can

of Diet Coke that I had been drinking.  I'm going to look for my checks, but
first I need to push the Diet Coke

aside so that I don't accidentally knock it over. I see that the pop is
getting warm, and I decide I

should put it in the refrigerator to keep it cold.  As I head toward the
kitchen with the Diet Coke, a vase of

 flowers on the counter catches my eye--they need to be watered.

I set the Diet Coke down on the counter, and I discover my reading glasses
that I've been searching for

 all morning.  I decide I better put them back on my desk, but first I'm
going to water the flowers.

I set the glasses back down on the counter, fill a container with water and
suddenly I spot the TV remote.

Someone left it on the kitchen table.  I realize that tonight when we go to
watch TV, I will be looking for

 the remote, but I won't remember that it's on the kitchen table, so I
decide to put it back in the den where

it belongs, but first I'll water the flowers.  I pour some water in the
flowers, but quite a bit of it spills on the

floor. So, I set the remote back down on the table, get some towels and wipe
up the spill.

Then I head down the hall trying to remember what I was planning to do.

At the end of the day:

* the car isn't washed

* the bills aren't paid

* there is a warm can of Diet Coke sitting on the counter

* the flowers don't have enough water

* there is still only one check in my check book

* I can't find the remote

* I can't find my glasses

* I don't remember what I did with the car keys.

Then when I try to figure out why nothing got done today, I'm really baffled
because I know I was busy

all day long, and I'm really tired. I realize this is a serious problem, and
I'll try to get some help for it,

but first I'! ll check my e-mail.
