In today's Miss Manners column, advice columnist Judith Martin responds to someone who isn't sure if they need to send a thank you note for a gifted bottle of wine.

I let a young couple I know use my vacation house. I asked them to bring me the used sheets and towels after their stay, since the laundry facilities at the house are unreliable. They did as I asked,

They did as I asked, and also left a bottle of wine with the linens. I assumed our transaction was finished. However, I just got a note asking if I had received the wine, implying that I owed them a thank-you.

Yes, but Miss Manners notices that there are two letters of thanks missing here. You have made the common mistake of believing that a present given as a gesture of thanks does not require thanks in return.
