Funny. My wife can recall and recite the smallest details, from as recent as an hour ago or as far back as 30-plus years ago. However, there are certain things she cannot remember at all--or see for that matter.
We have a home calendar too. Had one for years. I jot down 'NFL Draft'. I mention it at least once a week for a couple of months before the draft. What's my reward for letting her know ahead of time about the draft? Answer: She asks me "Is that today?" each day of the draft every year.
My wife records CBS shows, so I try the same thing before the NCAA Basketball tournament each March--although not always using the calendar. Like clockwork, she pulls up the DVR playlist, scans it, and says, "Where's my shows?" My response? Two words. "March madness."
She cusses every time.
