When I was about 5, I was peeling the skin off of my mom's back ( she had a bad sunburn ) She was wearing a strapless bra at the time, but it really confused me from looking at it from the back ( because it didn't look like her regular bras ) So I asked her "what it was"...and she said "Guess?" and I thought for a minute and said "A tampon?"
She went into minor shock for a moment and quickly changed the subject. I, of course, had no clue whatsoever.
