I had a courier run up to me the other day. He said he had a letter for me--per normal. But instead of a letter, he gave me a book. The Real Barenziah Vol 1. I was like, "...huh?" I've never had that happen before. Is that something that can happen sometimes? The couriers give you an item instead of a note? It's not a bad thing--just, I've played almost a thousand hours of Skyrim and I've never had that happen before so I was curious.
