Only you Aussies would even consider using that flip-flop for smacking real children.
It's heel is way too fat, the wide point is far to far forward and the rocker line is a right dud.
Back in the day we used to smack kids properly, real smacks, not the soft mushy smacks you lot do. Do you even know what a real smack is ? I bet none of you have even had a real laydown smack.
I have been smacked by Peter, Paul, Mary, Mitch and even Lee and Dee. They were real smackers, whether it was at LSD, THC or ADHD. Right up and down the north-south coast and out on the islands.
Yeah, you Aussie's have your fat, wide thongs for your fat wide feet, but tell me, who these days makes real flip-flops like that anymore ? No-one.
