Alright guys, I have another one of these threads for you.
A few weeks ago I was at a flea market and came upon a stand selling used DVDs. I found a few I wanted to buy and put them on the table to have the dealer count them and give me a price. I noticed I put it on top of another dvd by mistake. I am not sure if they counted that dvd or not but I am fairly confident they didn’t, but I absentmindedly picked it up with the rest of the stack and put it in my bag. The seller either didn’t notice, didn’t care, or counted it all along, which again is least likely iirc. I didn’t notice I had taken the extra dvd until I got home. I really and truly didn’t want it, least of all to steal it, and didn’t know I took it. Unfortunately there is no way for me to find the seller to give it back/see if I paid. Did I steal that dvd, and if so was it a mortal sin? This has been bothering me for weeks.
