The weather, it gives us something to talk about or we might start discussing our feelings.
5he compactness if the country as you can usually be somewhere nice relatively quickly. You get a better perspective on this when you talk to Americans. "We're just nipping out to see Stonehenge." "It's hours away you mad Yank." "So just a short drive then." I was invited to an art exhibition in Istanbul, all the Brits I told rolled their eyes at the idea and the American I mentioned it to went "so did you go? I'd fly that distance home if I had nothing else planned that weekend."
Our sense of humour, because of we weren't laughing we'd be crying and that's not the done thing.
