Well with thoughts and poems like yours i don't seem it is remotely possible your head is empty. Never-the-less sweetie this was quite a brain-racking poem; but one i enjoyed reading and trying to figure out.
[Btw if my comments and votes are late it is because of the red marker thing, it still isn't showing up in my fav's.]
i think you wrote three new ones as i was gone, but thats my guess because it doesn't show up on my favorites list! none do! but anyway i am only back until the end of this week and then i'm gone another week :( so sad! wonderful poem! loved it, cool idea but your head isn't empty it's filled with great thoughts of opening and closing cases, right?! lol
