behind-the-scenes at the theatre

I don't think I've heard so many curse words (mostly beginning with "mother" and ending with....well, you can guess) as I did today at the theatre while sitting, solitary, inside the theatre, reading a book about the Brontes before patrons were due to arrive. The conversation was between a stage hand and the sound guy. They were commiserating about a particular member of their staff -- a musician -- who does not appreciate how loud one of the actors sings as it interferes with the sound of his particular instrument. The stage hand did not appreciate this and I was privy to a 20 minute berating of the guy while pretending to read my book. It is unnecessary for me to relate the exact words that were spoken as so many of them were of a coarse variety that there is not much substance to share. All in all, I was greatly amused by it.
