Emptying my pocketbook, except for essentials, every time I go out for an evening or travel out of town.
Many years ago, my then-boyfriend’s mother got purse-snatched while she was walking outside a theatre. She learned a lesson that she shared with me – don’t always bring everything that one would carry for day-to-day activities. That evening, she might have needed her keys, driver’s license, a comb, some cash, and maybe one credit card, but she certainly didn’t need her checkbook, library card, address book, full assortment of credit cards, frequent-buyer card for the market, etc., etc. She lost everything and went through great trouble and effort to get replacements.
