We're trying to create our list for save the dates and it's turning out to be more difficult than we imagined. We have some cousins who are adults but still live at home with their parents. Some even have significant others who we will be inviting as well. Do we just send one general STD to the household, or do the adult cousins get their own? If they do get their own, would we just address one to "The Smith Family" or "Mr. & Mrs. John Smith" and the other to "Joe Smith"? Ahhh so complicated!
