There's this voice in my head that often asks for an (detailed) explanation of something that I already know or remember, and I pretty much will always answer it, sometimes even aloud. I would guess this voice (which I refer to as "you", which is me) is my common sense, but if that's the case, it would have the common sense to stop asking so many questions about something I already know the answer to. This voice usually only pops up right after I learned something new in a show or movie or sometimes a game, but it's still annoying that I have to explain something I already know to myself. I think I may have a problem or something, or perhaps it's because I ask everyone else too many questions, either way, the voice has been around in my head for years, and I want it to go away.
