Funny you should mention that example. My husband and I ran into a bike tourer from Oz over here once, and being enthusiastic about bike culture, we were conversing and checking out her paniers. Husband asked "So, what's the one thing you couldn't have lived without on your trip?" She responded enthusiastically, "thongs!" We thought that was pretty candid of her--until she pulled out a pair with a smiling face. LOL!
