True, but when you get your period, you are automatically allowed get out of anything you want to, or to do anything you want to. Boring meeting? CAN'T GO BECAUSE I HAVE CRAMPS! Don't feel like hanging out with your friends? CAN'T GO BECAUSE IM ON MY PERIOD! Feel like eating 5 tubs of ice cream? That's ok because I'M ON MY PERIOD!! It's like having all the good arts of pregnancy minus the baby :)
I mean ... I'd rather do all of that stuff than dealing with period pains. Yeah I'm an introvert and hate people but I get TERRIBLE cramps and the emotional part makes my depression worse. So ... I'd trade period passes for never having one.
Usually between 2-4 but never longer than 6
