I used to carry a purse. I was and am very picky about what kind and I don't usally like pockets on the inside.
I have become acustom to carrying just the basics. If I am going to need more things like camera or brush or "other" things I will take one. I tend to loose them or they get stolen. here is what was in my pockets on Friday.
one pay check, my work keys (they clip to my belt loop) two cards , reciets, a zoo pass (I have know idea why).
