Hopefully it's not frowned upon here to dig up old posts and reply, but I think I'm going to be doing this a lot here if it's okay.
I also spent a lot of time with this huge shredder through the ages of 12-14. I really enjoyed it. So much better than studying all day when not being screamed at. There's endless stuff to shred around there. Papers, books, video tapes. A lot of it more interesting than what I had to study on course. Once I caught some skin on the thing while tossing some videos down the shoot and gave myself a nasty cut and scar down my arm.
That scar got me out of the Sea Org quickly and easily once I put a mind to it. Yeah I have suicidal thoughts and intentions, and look at this scar down my arm that looks like I messily attempted to slit my wrist. GOODBYE! I was out in 48 hours.
My favorite insult while I was in the SO was "go shred yourself." In the end, I guess I went ahead and shredded myself. Man am I glad I did. I think about this every day when I shred my unneeded mail in my own home where no one ever screams at me for not going Saint Hill Size.
