This is quite lighthearted compared to conversations with my friend Alex (i nearly typed 'convo' there with is a blatant oz-ism)
He could whinge for England about the decline of spoken English.
I saw an interesting article on 'upspeak' yesterday on the BBC. As in the trend towards raising the pitch/intonation of a sentence towards the end to make it more like a question.
No one can be sure of its origins whether its 'Valley Girls', 'Australians' or 'Sales Pitch'
