I'll admit I shoplifted a few times when I as young. Once when I was very little about age 5, and then a couple of times with a friend of mine, who was apparently a pro at shoplifting.
When I was little I begged my mother to buy me a new box of Crayons, because mine were all broken. My mother told me no. So, when I went to the store with my mother, and while she was shopping, I took a new box of Crayons and put them in my pocket, and just walked out of the store. When we got home, I quickly replace all of the broken ones with the perfect new ones. Then I showed them to my mother and told her I had "fixed" all of my broken crayons. Of course she didn't believe me, even though I swore over and over that I had repaired my broken ones. Finally, after about 1/2 hour of interrogation I finally admitted to her that I had taken a knew box from the store.
Furious, my mother called the store and told the store manager than her daughter had stolen a box of Crayons from his store, and that she was bringing me back to the store, so I could return them to him. She told him that she wouldn't blame him, if he called the Police.
Anyway, she made me put the new Crayons back in their box, and took me right back to that store. I was sobbing and terrified. First of all, I didn't want to go to jail, and 2nd want to give up those beautiful new crayons.
My mother took me right into the store, and made me tell the manager that I had taken that box of crayons without paying, and I had to hand them back to him. He stood there very stern, and grumpy and told me that he had just called the Police, who were going to take me to jail. I looked at my mother for help, and she said, "No help from me. You did this, and you will have to pay for your crime".
Of course, he didn't call the police, and finally he told me I could go, but he said I was never allowed in his store again. Even though I was only 5 I never fogot ANY of that experience, and I was never even tempted to take anything again......Until...I was about 15 and started hanging around with a wild girl.
She shoplifted all of the time. It was a way of life for her. So, finally I joined in with her and took a bathing suit and some other clothes. I did it with her twice, and it just made me sick inside. After the 2nd time, I told her I just couldn't do it again. To this day, I cannot even think of stealing anything.
I wouldn't worry that you are a bad parent, nor would I worry that your daughter is heading down a wrong road. I think most kids have shoplifted, whether they admit it or not, and most people grow out of that phase quite quickly.
