What the hell is that supposed to mean??!! Jerk!!!
It means that I have a reminder to know when her period will be starting and she is likely to be more emotional so I need to tread more carefully and think about what I say and do a bit more. Why is stepping lightly being a jerk when someone is more unpredictably emotional than usual (albeit on a predictable schedule)? It's not HER fault, it's biology and I am trying to be accomodating.
And yes, I am a jerk, but I don't think it's for that reason.
