Input: Text: i used to take the public bus home from school from grades 4 to 6.  one day i was waiting for the ol bee to pull up when i found something like a string and an odd plastic housing.  of course i pick it up. when i pulled the string, out came some strange cotton tube.

on the bus i went. it was really crowded that day and sitting in the absolute front row of seats which ran along each side of the bus was me, pulling this string in and out of the plastic housing.  i thought quite a mystery.

many many years later i realized little young me was playing with a tampon!.  but no, it wasn't bloody.

*face palm*

TIFU: As a kid IFU playing with a feminine product on the public bus.
