Whatever's on what I so euphemistically refer to as "my mind".
A friend was talking about a political article she'd read online and the comments posted about it. She looked at me and said "It was like these people were reading a different article than I was". My mind immediately went here...to the forums, lol. How many times have you mentally shouted that question while reading threads? Heck, lets be honest, how many times have you sat alone at your computer and asked it out loud?
It's not just that we take away different perceptions
