When i read this my mind wandered ( as it often does) and i thought of Rocky in 'the rocky horror show' . At one point Frank'n'Furter introduces his 'creation' Rocky to Brad and janet and Riff Raff says ' Yeah so named for the rocks in his head.' Ha Ha. I feel like i've been collecting rocks in my head all my life.

And it feels like my thoughts keep hitting up against 'em.
So yeah i have a rock collection. In my head.
