When I was 6 or so, my best friend Amber and I were trying to make playdoh with out a recipe, or supervision. We had dumped to much water in it, and dyed it red so it looked like a bowl of blood. Amber looked at it and said "This looks like a period", I thought she was weird since we had just learned about puncation in school and replied "Nuh-uh! Periods are at the end of a sentence.". Amber laughed and said "Periods are what you get after you have a baby!". I thought she was right since her mom had just had a baby, and belived her until I was about 9.
