Currently, to me the definition of tired is not paying a bill because I am out of stamps and then noticing after a period longer than a week that the envelope I have to pay the bill in is not only self addressed but also requires no postage if mailed in the United States.
They're eager to get their money I guess.
And I'm slow on the uptake. It even said in the letter (that I read) that the envelope was stamped.
(I also recently tried to put the cereal in the refrigerator and the milk in the cupboard, but that could happen to anyone.) :)
So . . .
What is your favorite or most current definition of tired?
