I'm amazed how many women leave their purses in grocery shopping carts and then wander off checking the shelves for food.
I've never been able to figure that out, either. Or the ones who leave their purses in their unlocked cars while running in somewhere. It's an invitation to steal.
Me, I only carry a purse under duress, if I don't have enough pockets for all my stuff. Mostly in summer, or when I've had to dress up for something. 95% of the time, I just keep everything in my pockets. And my wallet stays in my pants pocket, especially if I'm somewhere I'll be leaving my coat out of my sight.
