Don't judge a dog

...by its fur. Not sure this saying exists in English (until now!), but you understand what it means. Like yesterday when the train decided it was no longer good to go. Stuck outside Zürich, I wanted to get back to the city. And like in any type of "emergency" you speak to people. So I got to talk to this shaved head guy, with a ring in his ear. So totally not the type I would speak to in any other circumstance. Turned out he was half American, half Swiss and a really nice guy. Whaddayaknow? He even knew Zürich enough to walk me to another station so that I could get back. A gentleman in disguise...
