a friend from high school days is now a Facebook friend; she's having a private wedding ceremony this month and then a reception next month. She invited a lot of fb friends including me to the reception, but the invitation I received doesn't mention my fiancé specifically or a plus one at all, and it doesn't mention RSVP. Since any of my fb friends can see I'm engaged, and since apparently they want people to come without RSVP, should I assume my DF can be my plus one? Or should I ask the friend?
