I can elaborate on that story a bit more...
My friend only played about three songs worth on the piano, I don't know if he knew more than that or not. Regardless, he played the same little tunes all the time, a combination of chords that he came up with. He would mesh in and out of these songs in a never-ending loop, all while playing the harmonica. That first night, something about the incessant piano playing reminded me of Nazi music (whatever that sounds like). I got it in my head that he and his wife were something akin to Adolf Hitler and Eva Braun, and it was their evil Nazi plot to indoctrinate me with the music so that I would eventually play music...And in doing such, I would make a fool of myself...Thus their Nazi ambitions would be realized.
Oh yes, I nearly left out another interesting thing from that evening. "Bodywork!" My friend, hell, I'll just call him by name...Michael. At any rate, Michael was very much into yoga and the concept of the body operating as a system. He was into this progressive relaxation/stretching regime that he called bodywork...He used to be a coach, and he would use it to rehabilitate athletes, stretch them out, increase their flexibility, etc. At any rate, when you're stoned and paranoid, the last thing in the world that you want is somebody offering to "work" on you, particularly if that involves them touching you in bizzarre ways.
Yes, I was F*CKED up.

It's funny, because I would give just about anything to be able to play music now, it's been a few years since Michael passed away. It's ironic how petrified I was of him that first night, because he became my single greatest friend...I've never loved another man as much as I loved him. I guess it's fitting that I reveal his name, because if I continue to develop the discussion on drugs (and through that, revealing my own adventures), he plays an integral part for me. Don't worry Sesame, more stories and analysis is on the way...
