As it was said before, that's not really a surprise to me. It really IS what addicts do. While in active addiction, I stole and did whatever I needed to keep my habit going. It didn't matter who I hurt or upset in the process.
It sounds like a lot of people put expectations on te fact that no one would think about or actually steal it. This could have been easily avoided by many means.
Sure, it's unfortunate, but I am not at all shocked or surprised.
