I think I was called a nihilist today.

Not me, exactly, but rather a reference to "art-nihilism". Yes, I should know if I heard the words (or read them). I know art all around me - hear, feel and see it! Can't imagine living without the joy of art. But, the art I know is  not always hung on a wall or verified by expert appraisal.

Possibly the remark didn't matter anyway.
Eh, it doesn't make any difference!
