"For the sixth time in as many months, a woman has cancelled our dinner. In and of itself, a cancelled dinner is a trifle. The cancellations themselves were less surprising than the timing and the method. Did the women, all of whom are friends, give me time to make alternative arrangements? Did they call? Did they explain or apologise? Did they hell! Each of these grown women sent a message via text or SMS to my mobile telephone. Average warning time pre-dinner: nine minutes. One message arrived after dinner. When it happens six times, you wonder whether you have stumbled upon a phenomenon. The aberration becomes the trend."
