A childhood belief about periods

When my family and I where at a very nice restaurant,I chose to eat spagetti.It was really messy and I needed a napkin.I was like "Mommy I need to use the restroom."She was too busy talking and just simply pointed to where it was.I was like 7 so i felt like I was finally a big girl.Well earlier my mom gave me 50 cents to get something out of the quarter machines and what I got was something only worth a quarter,so I had a quarter left over.I had just began to learn to read and saw the word napkin in the bathroom. I used my 25 cents and wiped the spagetti sauce off and shoved the"napkin" in my pocket. When the waiter came to pick up our plates he asked me if I was done with my plate, I was like wait heres my napkin.I reached in my pocket and pulled it out and put it on the plate. Every1 at the table cracked up laughin, the waiter wasnt to happy!
