What aren't ya?!

What are you not?

Noone fuckin' emails me so this question is courtesy of Carl Baron. It's gold. How come, in Aussie lingo, when asked how you are, you reply how you're not? The below is a common example of a typical Melburnian conversation.

"How are ya?"
"Not bad."
"What you been up to?"
"Not much."
"Like me car?"
"Not bad mate!!! Not bad at all."
"Wanna go for a cruise?"
"Wouldn't mind."
(later)
"Fuck are we there yet?"
"Mate it's not far."
"How far?"
"Not long now."

Seriously. That's from your mates and all. Complete stranger's here will point out the obvious to strike up conversation. It's the only time a question isn't answered in a negative.

"Hey mate's hot innit?"
"Yeah", while you think, "Can you fuckin do something about that hey?"
