The more I read this, the more annoying it is.
I can't work out why his only concern is how the absence is classified at school. Not fussed about the missed learning. Not bothered about (like pp said) how the medical professional dismisses female health issues, including severe period pains. Not bothered about how this could impact his daughters for the rest of their lives. Just bothered about how attendance is recorded.
Makes no sense. And what's worse is that loads of people, probably, mostly women are signing it because 'at least its something'.
I wonder if the 'proud mother of fierce, intelligent and brave daughters' has an opinion on this.
