I hate not knowing where my body is in relation to well...my body, and the rest of the world..
I just smacked myself in the lip, HARD with my own nail. I wasn't meaning to be that close to my face, I was reaching for something on the computer...and I have no idea how my hand decided to do that. This also fits with my ability to run into walls, misjudge doorways, trip over invisible objects etc.. if I just keep telling myself its a skill, maybe I'll feel a lil better about the insane frequency I do these things. lol Twice in my pre-teen years, I ran into the same wall (misjudged the doorway to the hallway), one of the times I did it so hard that I gave myself a mild concussion and had the pleasure of going to the doctor the next day with mom (who suspected the concussion deal) and admitting what happened.. (I was all of 11 yrs old at the time).
I like to think that walls and furniture just jump out at me and cause me to run into them.. they just move so fast no one else can see them ;)
