I don't carry a purse.
In fact, I've pretty much never carried a purse. I own two purses. One was purchased in KoreaTown in Los Angeles, because it was cream and blue, which were my two favorite colors at the time, and I liked that it was canvas, because it went with my shoes. Currently, that purse is serving as a crayon bag for church. I really have never used it for much else. The other purse has become almost exclusively my Disneyland purse. It's just the right size for a camera, a map, a bottle of hand sanitizer, and all the sugary snacks I end up buying.
Which brings me to my second point. The kind of stuff I would carry in a purse is pretty much exactly what a little kid would put in there. And I say "kid" and not "girl" because I'm pretty sure the contents would be closer to what a boy would carry around, if that sort of thing wasn't so frowned upon. Pretty much the only thing I need that doesn't fit into a wallet is candy and maybe a Nintendo DSi.
So yes, I do carry a wallet. In my back pocket. I recently bought one from Old Navy that holds a debit card, a Target gift card, and my ID. When I used to have cash, I carried a manlier wallet made of brown fake leather. I didn't apologize for it. It did its job well.
What I'm wondering is, what on earth are you people carrying that requires a whole bag? Even when I had a diaper bag, I still only carried around diapers and wipes and MAYBE a rattle or a pacifier that never got used. My mom had a purse, but it seemed like the only thing she put in it was gum and pennies. Sometimes she had lipstick, but I never saw her put it on any other time than in the morning in front of her mirror.
I am stumped by purses. Enlighten me. Otherwise, I'm calling your bluff, and next time we hang out, I'm going to have to insist that you share some of your candy.
