Not a problem, I can help you improve your English. First thing is in your interests here. You wrote: I would like to improve my English and meet a friends. But the correct is: I would like to improve my English and meet friends or new friends, which is better, since you are not here trying to find friends that you already have.
And do not forget, a is used in the singular form. e.g. I have a friend who lives in Australia.
Not a Problem Cris, is hard to write in English sometimes, specially when we are talking about Brazil. I did not know that you were living in Japan! If you come to Australia It would be a pleasure to meet you and guide you around! Do you speak Japanese? I don't know if I could survive in Japan...hahaha
Good to know that you liked my blog, I have to find time to write more, though.
You are absolutely right, when we decide to live abroad we have to stick with this idea and make it positive, otherwise the pain would be bigger than it already is.
Nice to meeting you!
