I am going to send out an invitation to my aunt & uncle who live far away, and my 3 cousins (ages 16, 18 and 20) live with them. I think each cousin has a "significant other" and I'm wondering if the SOs need to be invited? I want to address the invitation as Mr. & Mrs. John Smith and family but I really don't want my cousins' SOs to come. Otherwise that family will be taking up 8 spots on my guest list!
So do the kids' SOs have to be invited? Also, I have never met their SOs. Hell, I haven't even seen my cousins in 5 years. Maybe they just won't come at all.
But, what is the proper way to address their invitation?
