You stayed at your friends? house when you participated in a business seminar in Australia. You left a file with important documents in your room. Task: Write a letter to your friend, describing the file and ask him/her to return it to you by post. My dearest Philip, I am sorry I am writing only now. Firstly, I would like to thank you for all the (attention) and support you gave me while I was in Sydney. Things like that are (priceless) and all I can give you is my gratitude. I expect you and Ingrid to come to Rio soon, so that I try to somehow propiciate equaly joyful moments as those you (propiciated) to me. I am writing also, because of the fact that I forgot a very important document in the room I used in your house. This document is a signed contract and was the most important reason of my trip to Australia, after the business (seminar) I attended. You certaintly can wonder how desperate I have been in the last days looking for this document midst my (luggage). I could not find it anywhere and am sure I left it in your house. Please let me know if you find it, and post it for express (delivery) as soon as possible. I will pay for the (expense); just let me know what is your bank, (account) and branch numbers. With best whishes, Leonardo
