I rarely carry a purse(handbag). Most of the time my wallet and my keys go in my coat pocket. If I'm not wearing a coat, then my bank card and my keys go in my jeans pocket.
If I do carry a purse though, then it has my wallet, years old receits, some makeup, pens, paper, business cards from wherever and whomever, hair bands and elastics, sunscreen, bandaids, restaurant candies, loose change... and whatever else has been lost in their for years at a time.
Peace,
tammy
