Why is it?

Why is it that I can never do what I'm supposed to do when I'm supposed to do it? When the baby is asleep do I do my exercises that I keep putting off??? Nope, not me! I clean the kitchen...which in my defense did need cleaning. I admit I've been a lot better lately about getting things done. Thanks to Flylady my sink is now shiny and at most I have two meals worth of dishes to do at a time as opposed to a weeks worth a month ago. And yet its Sunday night and my family is asleep and am I asleep at 11pm. Not a chance...I'm reading blogs...I think I might be addicted...
