Dear Mark,
I hope that you’re doing well. Thanks for having me for the holiday. I’m writing to let you know that I forgot something at your house, and I need it back.
First off, I’d like to thank you for showing me around during the holiday. I had a really fun time exploring the city, and it was great seeing you and spending time together since we hadn’t met in such a long time.
Unfortunately, when I arrived home, I realized that I had forgotten my wallet at your house. I was in a hurry, and I didn’t notice that it was missing until I reached my apartment.
It’d be great if you could ship it to me via the postal service. They can deliver it within two working days. Don’t worry about paying the shipping fees, as I will pay them in full upon delivery.
Again, thanks a lot for the fun time we spent together, and sorry if this will cause you any inconvenience.
Best wishes,
John
