Reader Question: "If you are writing a business letter going to Jane Doe in care of John Doe, would you use Dear John or Dear Jane for your salutation?"

“In care of” helps the post office deliver mail correctly, with no confusion about addressee or address, and enables someone traveling or moving or residing temporarily to receive mail at a designated permanent address.
