      ‘So, Adam, you have the privilege of being my first Seppo.’
      ‘Your first what?’
      Seppo. You′ve gotta learn to speak Aussie, man. You′re a Yank, so –’
      ‘No, not a Yankee. I′m from –’
      ‘The You Ess Ay. Makes you a Yank. Yank rhymes with septic tank. But we like to shorten names and then add an O at the end - but only if we like you. So Yank is kind of neutral. Septic tank is rude. But Seppo, well, it′s affectionate. Get it?’
