I am an Idiot

What is the definition of an idiot?

I am covering the holiday today.  I am required to work in a building other than the one in which my desk is located.  The cafeteria is closed, and we are not supposed to leave the building as there would be no one else to cover our calls while we are out.  Therefore, we have all been asked to bring a lunch.

I got up early this morning and made myself a bag lunch.  A nice deli chicken sandwich.  A bag of green grapes.  A handful of little mini kit-kat snack sized thingies.  I put this together and then put it in the fridge while I did my normal work-day morning routine.

Then I left for work.

My bag lunch is still in the fridge.

IDIOT!
