I was about 8 years, and I heard some friends talking about the period. I asked what it was, and the answer was:
"You bleed in your bottom. Only girls can get it"
I was like:
"Cool! I'm looking forward to get the peroid!" I thought we girls only got the peroid once in a life. And then: Finish with it.
I'm not that stupid now.
