Everybody described the conscience as a "little voice in your head", so I thought that *all* thoughts were from the conscience-- essentially, I mixed the conscience up with the internal monologue.
I had (and still have) a lot of random thoughts, and when I was a kid, I was often told that I was very well-mannered for my age, so I thought that because I was so polite, my conscience was "bored" and just said random stuff.
