Call in the desert

At the spa, I pitied this very fat woman that was collapsing under the regime imposed by her trainer. Probably would have collapsed even without a trainer.  At some point I walk past her and she calls: Wait. Wait. Let me read.   Don't bother I said. It was the text on the T-shirt brought by my wife from Scottsdale. If a man speaks in a desert where no woman can hear is he still wrong?
