Although I am a Brit, my husband grew up in Napier, New Zealand. I know New Zealand is not Australia, but his memories of the place reflect your messages,Bloss and Bells - the friendliness, the freedom etc.
When his family returned to England, in his early teens, he was sent to school in Oxford. He had great problems adjusting to the English way of life. He had been used to riding a horse to school, and going barefoot all day. Suddenly he was the outsider at an English public school. He hated every minute of it and joined`the navy at 16 years old.
Whether it's his New Zealand upbringing, the Navy, or his character, he is, IMO, unusually sociable for an English person, and makes friends in the wink of an eye.
Bloss, I found it so sad that you had only been inside three English homes during your three years in Oxford. But also quite believable. My home town is Cambridge, and, having lived in London, I look back on Cambridge as a staggeringly unfriendly place in comparison. IME, twentysomething university students, other students (of which there are many) and non-student long term residents mix very little. Even my husband found it hard to get past the conversation stage with strangers.
Just a question for you all. My husband loved 'Milo' as a child in NZ. As you may know (assuming it's also around in Australia), it's a vitimin-fortified chocolate mix to add to milk. Recently my husband located some in SE London, and my toddler is now addicted to it. I'm sure the sugar content needs watching, but that aside, exactly how healthy do you think this drink is?
