Packing for Irish weather

I was doing some research on things to bring, and coming across a million and one people who write to dress in "layers" and bring raincoats and whatnot. Then I found this.

The Irish attitude to weather is the ultimate triumph of optimism over experience: Every time it rains, we look up at the sky and are shocked and betrayed. Then we go out and buy a new umbrella.

This makes me happy. And for some reason reminds me of a book title I saw on our shelves once: The Improbable Irish. I'm not sure how, but there's a relation in my mind. Also, what a brilliant title.
