There's a very useful word used by a lot of Indigenous Australians.. "unna"
Depending on how you say it, it can mean..
"is that true"
"no, that can't be right"
"yes, I agree with you"
"do you agree with me"
"are you sure"
and various other phrases.
“Life is not a journey to the grave with intentions of arriving safely in a pretty well-preserved body, but rather to skid in broadside, thoroughly used up, totally worn out and loudly proclaiming ... WOW! What a ride!”
