Most embarrassing situation
It was just after I got my first period on the previous sunday and my mother had called the school ( it was monday ) to tell them that I had my period and to give me reminders the whole day about effectively changing my pads.
I was pulled out of class several times by teachers to say "Congratulations you're a women now."
The class aids every staff member knew and the principle and all the male teachers congratulated me as well.
It was one of the most embarrassing and awkward things I've ever gone through in my life.
