It is sort of like the difference between a mental patient and a neurotic. You can just tell the mental patient is more then a little off and can't quite put your finger always on why. One thrives professionally and the other in an institution. But there is no doubt which one is which and this was true of his piece.
Maybe it is intuitive on my behalf. But the obscure "Honey Poo let's go do it doggy style like you like," rang sick, sick, non-writer play to me. It was too out of the blue even for the play. (It didn't feel like parody or anything like any other writer technique.) The chainsaw or whatever out of the blue by the mom in the play exceeded the obscurity of American Psycho (which I loved by the way.). At least groundwork was laid for the main character picking up a chain saw in AP, here an obscure side character who is not even raging picks it up. There we are again the thin line crossed. This all leads to no meaninfl resolution, just death.
Whacked, whacked, whacked. If I was a student and reading his work, combined with the personality type described I would go to admin. But you know what they say about hindsight. I think the admin failed miserably on many counts.
