Dear Mr Smith,
I write to you in order to inform you about my sunglasses that went missing while I was on vacation at your resort. Unfortunately, I’m not sure about the location I might have a lost them, but I would like you to search for them because they are very special to me. Their color is red and they were in a yellow case. Also the case has pink flowers and my name is written in gold on it. Please write me back if you find them or if you have any information about my missing items.
Yours faithfully,
