It seems important to you that the Ouija board not be implicated here. Am I reading you correctly?
LOL, no...it was just in reading the article, they were trying as hard as they could to implicate the Ouija board!
I remember someone unfortunate in my family got one for Christmas back in the Sixties, and after being inveigled to play this in some darkened room with a candle, looking at each other and thinking “Okay. This is utterly stupid. How long do we have to do this?”
