"Julia," Dad ventured, "Why doesn't your Mom have a sparkle on her flip flops?"
"Because I paid too much for mine."
Jody thought this was a very Dad-safe answer.

We then proceeded to enlighten my dad of Aussie thong-wearing habits, such as:
With a suit, boys and girls, on the way to the office
On the way to a party, heels in hand
Post-party
Year-round
The suit phenomenon is quite something to behold. Well-coiffed men and women downtown or walking across the bridge, dressed and pressed and accessorised... wearing flip flops.
