When I was about 7, I met a blonde woman who had a redheaded baby. After she left, I exclaimed to my mom that she must of stolen the baby. When my mom asked me why, I told her because the baby had red hair and the woman didn't. Therefore, in my mind there was no way that baby belonged to that woman. My mom tried to explain that children don't always have the same hair color as their parents. Which to an extent I believed because I was blonde and my mom a brunette but because redheads were so rare to me, I just "knew" that only two redheads could make a baby with red hair. I refused to believe otherwise.
