Bag man seems to be internationally known and not just an Australian expression. From Wikpedia, A bagman is a person designated to collect or distribute illicitly gained money.
Yet how is a bag lady not the same thing? A bag lady is a destitute old woman who sleeps on the streets and carries her belongings around in bags. Nothing like a bag man. So queer.
Also queer to me is the odd pronunciation by some British people of words like book and cooker, the latter being what we call a stove or oven or hotplates. I am trying to think of something that rhymes with the way some British people pronounce the words, but I cannot. I can't even do it in writing. It is an alien vowel sound to Australians and probably to many English people too. It is not quite right but try bewk or cewker. Weird!
Years ago when I used to go on to gay chat lines I came across someone who I enjoyed chatting with and in a moment of indiscretion I divulged to him where I worked. Ah, he said, you would know A****. A is a tall Spanish looking Filipino who seemed to be gay to me. I asked the guy who I was chatting to, is A gay? Oh yes, he said. A is definitely gay. He said then with such confidence that I know A....well, no need to go there. I should have gone on to ask him how A being gay sits with his strong Catholic beliefs. A used to send us Christmas cards, always with a God Bless at the end.
A is now married with two young daughters. He still looks quite good as he enters his forties, but he does not change his fabulous hair weekly as he used to and now it is of a 'sensible' style. Not long after it was confirmed to me that A was gay, A's photo popped up in the gay press out at a venue.
To more recent times, at work A was asking advice from a non first language English speaker about a word. Andrew Big Ears immediately tuned in. The advice A received was kind of wrong without being wrong.
I wish I could remember what the word was now, but I cannot and later I corrected A. I said something like, while it is not wrong, this is the better, shorter and more concise word to use.
I went on to tell A about my pet hate of people saying orientated. Orientated is quite correct, but why not just say oriented. For mine, they are the same and I don't know why you would use a longer word when a shorter one will do. While I know I am right, perhaps you can explain to me why orientated might be a better word to use than oriented?
God help those who are not English native speakers and weren't brought up with the language. Even I don't understand my own language, and one can only resort at times to saying, no rules, that is just how it is.
