IELTS Letter, topic: Personal, asking for the forgotten file

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 {tooltip}propiciate{end-link}propitiate{end-tooltip} joyful moments as those you {tooltip}propiciated{end-link}propitiated{end-tooltip} to me. I am writing also, because of the fact that I forgot a very important document in the room where I stayed at your house.

The document is a signed contract and was the most important reason for my trip to Australia, after the business seminar I attended. You {tooltip}certaintly{end-link}certainly{end-tooltip} can imagine how desperate I have been in the last days looking for this document in my luggage. I could not find it anywhere and now I am sure I left it in your house.

Please let me know if you find it, and post it with 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 wishes,
Leonardo
