Dear Mark,
I hope you are settling back into your routine after the busy week of my seminar. I had a wonderful time staying with you, but I have just realised that I accidentally left a crucial file behind in the guest room.
The item is a slim, navy blue plastic folder with a clear front cover. Inside, you will find several printed spreadsheets and a few signed contracts related to my upcoming project. These documents are vital for my presentation next week, so I am quite anxious to get them back.
You should be able to find it tucked away under the bedside lamp on the small wooden desk. I must have placed it there while I was packing my suitcase on Sunday morning. It is quite easy to miss, so please check behind the lamp base.
Would you mind posting this to me? I would be incredibly grateful for your help, and I am more than happy to cover all the shipping costs. Please let me know the amount, and I will transfer the money to your account immediately.
Thank you so much for your hospitality and for dealing with this inconvenience.
Best wishes,
Sarah
