Dear Mr. Henderson,
I hope you are having a pleasant week. I am currently busy finalising the arrangements for a surprise birthday celebration I am hosting for my close friend, Sarah, this coming Saturday evening.
Since I am expecting about fifteen guests, I find myself slightly short of seating and serving equipment. Would it be possible to borrow four of your folding chairs and your large punch bowl for the night? I know you mentioned recently that you rarely use these items, so I thought it might be acceptable to ask.
I will ensure everything is cleaned thoroughly and brought back to your doorstep by Sunday morning, around 10:00 am. Please do let me know if this causes any inconvenience; I would be happy to make alternative arrangements if you need them that weekend.
Thank you very much for considering my request. It would be wonderful if you could drop by for a slice of cake on Saturday night if you are free.
Best wishes,
Alex Thompson
