When I was around 8, before I ever had "The Talk", my Aunt was expecting. We were at a picnic and she had a mis-carriage, but it looked like her period to me. Everyone wa stalking about her having a mis-carriage and losing her baby. When I had my first one, I screamed for my mother and told her I had a mis-carriage. She laughed so hard she fell down, and finally explained it to me. I was 13 before I finally learned the truth.

My friends' mother use to call having her period "When the river runs red". My friend lived next to a small stream, and use to watch it everyday to see when she'd have hers.
