I did it as shoplifting a few times when I was 18 years old right after leaving home. I had been raised by a very unsympathetic, sometimes cruel, mother and I wanted to know what it would feel like. I felt quite guilty so I stopped doing it.
Years later I sent money and an apology to one of the stores I had solen from. I am not a thief and I am sad and sorry that I acted like one.
