Translation of Nonchalance

Do you know any people in Australia. I have delivered all the necessary information to the friends. Please give them a few more days to correct the letters (I was not in the office last week).
I went back to the busterminal and dressed for the ride. That means I put on long pants and my hiking boots. Friends have warned me about freezing conditions during bus rides because of airconditioning.
Sorry for bothering you with so many questions. You are going to be my first online language course. The more I trust you and your website, the more I will use it and recommend it...No problem...
