DEAR ABBY: I'm a 28-year-old mother of two. My teenaged adopted sister steals makeup from stores. It sometimes happens when we are together, but I never catch her doing it. She has told me she feels no remorse about stealing the items.
My parents and I have lectured her time after time. She's now claiming her friends give her makeup they don't like. I'm exasperated because she just doesn't seem to get it. Would it be wrong of me to tip off the security guard on our next shopping trip? I want her to learn a lesson before it's too late. Yet, it could result in juvenile detention and a financial burden on my parents.
