Nice poem - let me exchange you one I saw yesterday and really liked, though the philistines around me all pronounced themselves unmoved; I'm not going to type it up here but I'll put it on my journal.

Looking at the definition and Usage Note of "disinterested" I think I used an appropriate word...I've always been more of a descriptivist than a proscriptivist, despite what 89% of the Usage Panel says, and "uninterested" would have just sounded lousy in that context. "Apathetic" might've worked though.
