Must be a women defect. They all seem to to it. Some come with an optional "don't forget I'm out tomorrow night" setting that when questioned as to how you'd forget something you weren't told about responds with "it's in the calendar".
I especially enjoy the "You don't mind if I go out tonight do you?" just as she finishes the hour long bath/getting dressed up/doing hair/makeup etc ritual. Like it's actually a question at that point. Because of course if I say "Yes I forbid it, woman", she'll take off all the slap and just go and clean the cooker or something.
