Dear Annie: Things disappear when sister visits

Dear Annie: My twin sister and I are 57. Every time she visits me, she takes things. Often, I don’t realize the things are missing until I need to use them, or when I want to wrap them as gifts, which is what happened last Christmas.

When this has happened in the past, I’ve confronted my sister, but she denies taking anything. However, during my last visit to her new home, I caught her. I was hanging up my clothes in the closet, and to my shock, the top shelf had several of my missing things. I called my sister in to explain, and of course, she couldn’t lie about not stealing the items I could plainly see.

I’m financially better off than my twin, but she does quite well, too. I have always been there for her when she needed anything. She lived with me for several years when she had nowhere else to go, and I helped her get out of debt.

My brother also steals from me when he stays here. And when my sister came last week, after she gave me her word that she could be trusted, I discovered several items missing. Is there a reason people do this? – Kansas Twin

Dear Twin: Your twin (and your brother) may suffer from kleptomania, an impulse control disorder that makes it difficult to resist urges to steal items that, for the most part, you don’t need and won’t use. Your risk of developing this mental health disorder is increased if you have a parent or sibling with kleptomania, obsessive-compulsive disorder or a substance abuse problem. Your siblings seem to qualify. You can talk to your sister, saying that you are worried about her, and suggest she ask her doctor for a referral to a mental health professional. We hope she gets help before she steals from someone who will have her arrested.
