My friend Lauren was totally misinformed about periods. We were talking about puberty one day, and I told her about my friend who'd been on her period for a few years. Lauren was like, "What's wrong with her?" I was like, "Huh?" And she then proceeded to explain how girls only had their period for one year after they started. (Mind you, she was 10 at the time and already knew about sex and everything.) Anyhoo, I told her that no, girls had their periods until they were about 50-60. Lauren argued that her mom didn't have a period and she was only 35. Then, out of nowhere, Lauren's 16 year old brother (who had been listening to our conversation all that time) said, "Yeah, well, mom's had a few operations." An embarrassing way to find out, but at least Lauren now knows the truth before she starts her periods.
