So, a little background info. I was like 5-6 at the time, and I had seen my mom use feminine products before. (She kept me in the bathroom with her, so I would go around messing shit up.)
This one time; I was in the bathroom with my mom. I wanted to be a good little child and get her a tampon. Long story short, she wasn't on her period. So when she told me she didn't need it right then, you could probably imagine how confused I was.
I don't know why I thought of this now, but I did. I now know why she didn't need a tampon, and I'm still embarrassed to this day.
