One time I was in country Victoria for work, and had been driving for hours in the rain. I was a bit frazzled as I went into a country bakery to get a sausage roll for lunch, but the old woman behind the counter said "Its good weather for ducks" by way of greeting. I'd never heard that phrase before but thought it was such a good one I bought a lamington too.
I wish I hadn't put off bringing the washing in though. Oh well.
