Also, I just want to add that when I said you "lacked imagination", I wasn't trying to imply that you are essentially incapable of imagination. I've thought a bit about that phrase, and I think it's not great, and I should find a way to say that a person has not yet imagined that world, because that's what I really mean. "Lack of imagination" could mean that, but it's obviously a confrontational way to put it and I'm sorry I phrased it that way.
