This is how this read in my head.

'Tis what I meant.
I have family I consider Australian because I'm unlikely to meet them again, despite one being English and the other Kiwi (and my cousin, who really is Australian.

Ah. Never mind. :bolt:

I don't mind you, Pete.
But I do mind you.

I was just bragging on my Bringlish skills, but I don't quite get the implication in the last line. It's flirty, right?

Nah, just silliness. really.
To "mind" someone is sort of to be wary of them. Or get them to be wary of you. Or just listen.

I say to Diz all the time, "Mind yourself. MIND yourself now!" when he gets in my way and I nearly fall down the stairs.

So it's a way of saying I take what you say seriously.
But hey, flirty I can do ;)

If you were a milkshake I'd suck you so hard I'd give both of us a headache. Oops, no. That's just rudey.

Oh my. I need a cold shower now.

I'd say you have masters in flirty.
