Mr. Distracted

So, according to a number of sources close to me, I am the most distracted, attention-deficit affected person they have ever met. I have been slowly realizing that I am constantly tapping, twitching, fidgeting, humming, singing, and looking around distractedly--this happens even when people are talking to me. Concentrating is difficult for me because I tend to have so many thoughts floating through my pea-brain. A friend recently challenged me to sit absolutely still for 5 minutes--I was able to do it, but I swear it almost killed me! What does this say about me? It's not that I am not interested in what people have to say to me (most of the time), it's just that there is always so much going on around me...

If there are people out there who I have offended with my constant distractedness, please don't take it personally--to use a totally overused cliche, "it's not you, it's me."
