I can't think of any time that I've ever used a checklist. My brain seems to shut off whenever I see a list because lists are so tedious. I use my brain, never a list. That doesn't mean I've never forgotten anything.

I rarely make mistakes when I'm alone ... (but who would know, right?) Most of the things that go wrong are when there are others to distract and disrupt the routine. Sue tells me she got my sunglasses and my wallet .... but then we're driving home and I realize she didn't pick up my phone and neither did I! Well, she's going to get the blame ...
