Dear Brenda and Dan,
I'm writing to you, because I want to thank you for the invitation. Of course I accept it and want to discuss about some things.
First thing is what can I bring with me? I don't know exactly what kind of weather is in Australia… What should I be prepared - rain or sun? And how about norms in this culture - is any special cloths which I can't were?
I want to buy you a painting my favorite painter as a thank you for stay in your house, but I'm not sure if this will be a good present to you. Maybe you want something else?
My plane fly 22th June. I will be wearing a white top and red trousers so you can better recognize me.
I'm looking forward your answer.
Bye for now,
XYZ.
