This might be a bit TMI so if you can't handle it please do not read this.
Imagine this: you're in school and all of a sudden you feel something strange. You push it off as you just really need the bathroom. So you wait for the right moment to ask a teacher for the hall pass. You only manage to get the hall pass at the end of the day. You go to the bathroom and realise... you just got it. And you don't have any pads. And you don't have any black pants. And your school pants are beige... yeah. That happened to me. I just waited for the day to end and for me to arrive home and proceed to cry.
