He never does: he's trying to make it look like he didn't go to an exclusive private school and marry the GGs (the most expensively attired woman in public life?) daughter.
Probably loses something without seeing and hearing it but I chuckled at this footage of parliament on 7:30 report (
www.abc.net.au/7.30/content/2013/s3890391.htm)
"JOE HOCKEY, TREASURER: Be calm, OK? And I know you're excited on the first day. This is your best day in opposition, trust me."
He also fired a beauty across the bows of Wayne Swann:
"JOE HOCKEY: So I'd call on the Member for Lilley to write to the Government to ask that all correspondence between him and the Reserve Bank is released to the Australian people, and I tell you what, in return I'll release the letter from the governor of the Reserve Bank about the $8.8 billion."
True: pointless and unedifying but he has got a good comedic sense and opposition must be bloody awful. And even worse, after you've held the reigns.
