Here's how my thought process goes:
I can't make the bed because the sheets really need to be washed but there's a load in the dryer that needs to be folded first which I can't put away because there is already a basket in my room that needs to be done.
I can't make dinner yet because there are leftover corn cobs to be boiled with old carrots and a chopped onion to make homemade corn stock for the homemade corn chowder that I can't bring myself to eat when I make it because I'd rather have pizza instead.
I can't write that quote down in Molly's baby book because I stopped writing in it in July 2009 and I can't remember what else happened in the last twelve months which I need to catch up on before I write the other thing down.
I can't weed that square in the garden because then I'll get to the basil that needs to be harvested and made into basil dressing which I can't do because I'm out of apple cider vinegar and the girls need a bath before they go to Meijers.
