We are addressing our save the dates tonight and i'm confused on what to write on them. For married couples do I put Mr and Mrs John Doe? If they have children should I pur Mr. and Mrs. John Does and Family? For single people should I put Ms. Susie Doe and Guest or just Ms. Susie Doe? And for unmarried couples living together do I put Mr John Doe and Mrs. Susie Johns? Thanks for the help!
