the problem with the situation is that the person one is trying to convince is TOTALLY empowered. they can just (metaphorically) sit there with their arms folded and everything you produce they just go (winces).
and you find yourself, you know, scrabbling around trying to show things in their best light - making an ass of yourself. and then sometimes, just to keep the game going, they will chuck you a bone - "oh yeah that's ok" or "i quite like that"
and you can't make head or tail of why one thing passes their acid test and another doesn't...
it's a fool's errand trying to convince people of things like that. i always remember - pathetically - trying to convince my trance friends of the validity of jungle - and the pain it caused me...
