Canadian is polite but not friendly : version 2

Somebody correct some errors in my writing and it is really helpful for me.

제가 쓴 것이 반드시 정답은 아니고, 다소 제 마음대로 고쳐보았습니다.  ()안에 든 것은 빼도 무방하거나, 빼는 것이 낫다는 생각이 든 단어들입니다.

(저보다 훨 뛰어난 영어실력자가 보시면, 제가 첨삭한 것이 우습게 보일지도 모르겠습니다만)

Before I came to Canada, I have been to Melbourne, Australia and Washington DC, USA. These are my all experiences in the western culture. I did not have any special occasion when I was in Washington DC because I stayed at an isolated hotel attending seminars and having business meetings just for a week.

But I had many kind invitations from very friendly Australians during my three-week (long) business trip. They brought me to their home and I enjoyed wonderful times with delicious dinner and BBQ almost everyday.(이 문장에서는 invited를 쓰신 것이 전혀 잘못된 것이 아니지만, 제가 앞에서 invitation을 언급했기 때문에, 반복을 피하기 위해 고쳐보았습니다.)  I was impressed very much that almost Australians, who I came across on the street, were smiling at me and said hello to me.

I was excited before I came to Canada as I expected that Canadians (or a Canadian) must be hilarious like Australians(or an Australian).  But I was wrong, I guess.  Canadians who I see at (the) Calgary usually have moody expression like Koreans and they hardly exchange greetings. I was a little bit confused. (이 부분은 시제의 일치 때문인데, 아직 캘거리에 계신듯 해서, 현재형이 맞지 않을까 싶습니다.)

A few days ago, my instructor at LINC told us that Canadians are polite but not friendly.  I (can) quite understand now what he said.

There are many western countries and they are not the same even though they speak English and are the same common wealth countries.

When I am walking around the city, I am sometimes confused if I am still in Korea.

쓰신 글 내용에 대해서는, 도시의 규모와 분위기에 많이 좌우되는것 같습니다.

저는 인구 16만 정도의 소도시인 벌링턴에 삽니다만, 산책할 때마다 왠만하면 처음 보는 사람들이라도 서로 인사를 합니다. (물론, 모른척하고 외면하는 사람도 가끔 있습니다만)  하지만, 토론토에서 그러한 상황을 기대하기는 어렵겠지요.  그리고 아무래도 따뜻한 곳에 사시는 분들이 더욱 프렌들리 할 지 모르겠습니다.
