...a friend you know crochets and asks you if there's anything you'd like her to make, you send her the pattern of the uterus cozy. (forgive I would credit the lady that made the pattern, but I have since forgotten your name. :()

You resist the urge to laugh at anyone shopping furtively in the pads section.

I resist the urge to laugh EVERY TIME I WALK PAST the pads section! Mwahaha!

...you gloat when you pass by the "feminine hygiene" aisle.

...and then stop to wonder if the urge to do so is ever going to stop!

... your friend in need has to ask female strangers in a full pub if they have a spare tampon because you don't carry any despite it being your time of the month as well

... you just smile when your roomies rant at how much decent tampons cost and how fast the bathroom trash fills up when they have their periode

...you try to convert all female acquaintances (not just close friends) to cup usage! (I'm pretty open about these things ;))

...you become so comfortable with your bleeding that you talk about your cup, it's usage, and it's contents in great detail with other cup-converted friends.

... or to your parents. My father gets so horrified.

I boxed up all my pads and tampons in a shoebox and gave them to my girlfriend. I hadn't used them since before I had my son and only a small supply afterwards (I use to buy the really big super box of tampons and the multi pack of pads) so, I had tons and tons left over when I switched to my Diva.
The amount of drawer/cupboard space available in the bathroom is amazing! I only use a small corner of the drawer for my diva cup and diva wash,.. the whole drawer is empty when it use to be crammed full of "supplies".

.... you go into great detail about cups at the local all natural store because he does not carry cups or cloth pads and he really really should!!

...your roommates fight over who didn't roll up their used pad like they should have and they try to blame you, and you just smile serenely and say you haven't bought a pack of pads in almost three years.

-You keep harassing your Whole Foods to carry cups again.

...you come this close to asking one of your workers why she needs to take her purse if she's only going to the restroom. (That would have been embarrassing.)

You aren't embarrassed or uncomfortable talking about your menstrual cup article in front of your 65-year-old male journalism professor and all male classmates.

...you wonder what to do with your old stash pads.

...you forget you're on your period halfway through the day because the cup works so well!

... you feel so relaxed and casual about period matters, that when you forget your cup and do need to buy pads, you start throwing and catching the packet like a ball on the way to the till, then wonder why people are looking at you funny.

This is me.
*laughs*

... when you call your doc because you're bleeding too much during a period -- and you're able to tell them in terms of millilitres per hour.

Also, when you turn all your tampons into ghosts.
