Nothing big to report here. Not that I've never stolen anything ever, but nothing much and extremely rarely. My brother was a huge shoplifter in his teens though, he raided like half a dozen games out of Blockbuster, including Final Fantasy III (aka VI) which I am actually very grateful for because IIRC that's what introduced me to the series. He even stole Castlevania IV when we ALREADY HAD A COPY, how bizarre. This was the least of his exploits though, he used to wear huge baggy pants and I'm convinced it was as much to fit more stuff in them as it was a fashion choice.
But I was supposed to talk about my own sins. Well, my memory is pretty fuzzy on this one, but I remember I did something to my brother one time (I was probably early-mid teens and he is a couple years younger) and he was SUPER PISSED. He even came after me with a big kitchen knife and I thought he was going to use it, not like murder but I didn't want to get cut at all so I locked myself in a room where he couldn't get me until our parents got back. He was pretty crazy back in the day but I still must have done something pretty bad to get that kind of reaction.
