Dear Abby: “Cautious Bachelorette” (July 16) asked you how she should respond to a workman who asks if she lives alone. Having worked 30 years in a maximum security prison, I can assure your readers that criminals gravitate toward jobs that provide access to people’s homes as a way of scouting victims, so “Bachelorette’s” concern is well-founded.

I advise single women to keep a few articles of men’s clothing, such as a jacket, work boots and other items, visible in their homes. They can be purchased inexpensively at a yard sale or local thrift shop. When a stranger is invited into her home, she can simply pick up one of the articles stating, “Here, let me get John’s coat out of your way.” It does provide a very real deterrent to criminals or others looking for a single woman to victimize.

Dear Ronald: My readers agreed that setting the stage (with an invisible housemate) is an effective way to give the impression to outsiders that you do not live alone. Read on:

Dear Abby: Take a suggestion from a senior citizen who has lived alone for many years—and it applies not only to females, but also to males of any age. Singles should purchase articles of the opposite sex and display them prominently in their homes so they can be seen by any stranger who comes into their homes. That way, the question, “Do you live alone?” doesn’t come up.

—Safe Senior Citizen in the South

Dear Abby: I live alone and I keep a men’s magazine on my coffee table, a second set of towels in my bathroom and even went to the thrift store and bought a bathrobe that hangs on a hook behind the bathroom door. Also, I always speak in terms of “we” whenever I have a stranger in my home.
