Guilty as charged. It's not unusual for my DH and I to be watching TV and he'll ask me what a character has said and when I don't respond, he looks over to find me "zoning out". He usually snaps his fingers to bring me back to reality. LOL It happens a lot more for me when I'm tired. I am even able to do this at my lunch break while looking like I'm reading the paper as I did today. hehe My co-workers probably think I'm a slow reader or something as long as it takes me to "read" a section of the newspaper sometimes.

I think mine is more like Kelly's - sensory overload and I just have to take a break for a moment.
