The day before we were to leave for San Miguel de Allende, I decided, after brunch with friends, to lie down for the afternoon. I didn't feel quite right and thought a mild intestinal problem would be cured by a long siesta.
That's what I told myself anyway. We had non-refundable bus tickets and a non-refundable accommodation reservation for the next day in San Miguel de Allende, so I needed to buck up and get better. Fast.
