The plan was to buy everyone cake.My husband, Peter, and I are finally getting ready to leave Mexico, and we can’t say we are too happy about it.The last two months in San Miguel de Allende have convinced us that it is a place we want to return to, and now leaving it feels very hard—especially when my sister tells me about the freezing rain hitting her home right now.“We had to cancel our trip to visit Uncle Andy and Bea!” she tells me. “The roads were terrible!”As I sit in the evening sunshine, in a city where people usually don’t need to heat their homes and never need air conditioning, the idea of freezing rain does not exactly make me homesick.“Why are we leaving, again?” Peter asks.But I’m anxious to see family again.
