Brussels feels like “Capital of the EU and a bilingual region of its own — nineteen communes, each with its own tax rate”, while Dublinis “English-speaking EU with every US tech firm's European headquarters — if you can survive the rental market”.

Dublin — temperate maritime — mild, wet and windy year-round; rarely hot, rarely freezing.
