I was on a bus today and I overheard the guy behind me talking about The Silmarillion. He was discussing something with the guy next to him, who he had just met, and he brought up the quote where Iluvatar tells Melkor that everything he does is contributing to his plan. I didn't hear what they were talking about originally, because it only caught my attention when he said "ever read any Tolkien?" The other man obviously had not read it, so they didn't discuss it any further. The guy said something to me later, and I mentioned that I overheard him talking about The Silmarillion. We had a quick chat about that and HoME 10. He sounded very intelligent and educated and so I was kind of intimidated to keep the conversation going for too long. First time anything like this ever happened.
