Don't be alarmed. I ain't going down that road, this time at least.
From the balcony I just observed two young Asian men alight from a tram. One went to a rubbish bin and spat into it. I suppose this is a form of polite behaviour for our Asian students, rather than spitting on the footpath. No matter. I find spitting in public absolutely disgusting and not to be tolerated, whether on the street, the football field or into a rubbish bin.
So where do native born Australians learn this from? There is probably always an amount of it happening in school yards among the younger kids. I can certainly remember, but I don't think the 'play' continues into later years.
Undoubtedly it comes from the sporting field, especially ball sports, picked up by impressionable teenagers. It doesn't matter which code of football. It happens in them all and it ought not. Over to you, clubs and umpires, to stamp this out dead.
We can hardly lecture immigrants about spitting in public when they can turn on tv and see our sports stars projecting saliva and phlegm in all directions on the football fields.
Do your bit by glaring at or making a disgusted face, or even a sound of disgust at someone you see spitting in public.
I think I shall enjoy my old age as a grumpy old man.
Of course I could bring up the matter of The Bieber dribbling spit onto his fans below his balcony, but I would give far too much of myself away.
