Hi all! I am wondering how to properly address my STD for a married gay couple with the same last name. I looked on google first, and all of the examples had the couples with different last names or had inconsistent responses. I'm not sure if it would be appropriate to write Mr. and Mr. (First Name- who's do I put?) (Last Name). Or would Mr. First Name-Last Name and Mr. First Name-Last Name be more appropriate? I was hoping I could get a better consensus on here than google, which for once, was very not helpful!
