DEAR ABBY: Sister can't stop stealing things during visits

A woman seeks advice from Dear Abby after her sister, who visits monthly, repeatedly steals items from her home, including personal belongings like a hairbrush.

• Dear Abby received a letter from a woman troubled by her sisters monthly visits, during which items like a hairbrush and laundry detergent mysteriously disappear.
• The sister travels four hours to visit, bringing a friend and her husband, but the host now feels uncomfortable and suspects her sister of stealing, likening her behavior to a rat.
• The issue raises concerns about potential underlying problems, such as dementia, and the host questions whether to confront her sister about the laundry of missing items.
