My brother has been teaching English in Madrid for almost 16 years — probably the reason why so many Spaniards have a Cork accent. He brings my nephews to Bandon every summer for a few weeks. They love the Irish summer that we spend so much time complaining about. They love their lives in Madrid.

Recently, in an ordinary casual way, he remarked: “We might not stay in Madrid in the long term. April to September has gotten much hotter.”
