I have posted about this before, that I feared that certain guests who are only sent a "you" are invited will take it upon themselves to invite their bf or gf. We are only inviting LONG term, engaged, or married people as couples.My fears have started...........One of my guests RSVP'd to the engagement party with "me and ____ will be there".....the invite was for HER, not "them." She usually is a little, um...pushy (I think that is the best term), and is used to getting her way. My engagement party host said, "oh whatever as long as only 50 people show up and no more." Which is fine, that host is paying, not me..w/e... But it is an interesting comment given that the eng. party invite list had 39 (no kids, no bf or gf, just married and/or single)....if we add in their bf/gf/kids the list extends to about 65...........HUGE difference between the invited.A little early to be worried about this for the wedding, I know, but...........never to early to wonder how to handle it.So..........for example:Invite reads: (wedding)Addressed to: Jane DoeInvite says: Jane DoeResponse/RSVP card says: Jane Doe which entree?CLEARLY a 1 person invite, and she rsvp's withJane Doe and John Smith will bet there eating chicken (or whatever).Not married, we dont know that bf, they are not long term and NO one else got an exception.Sorry bout the length, but................Advice? Do I call her then and tell her that although we would love to invite the world, we can't (politely) and that the invite was for her only? (politely) Can I address it now, politely (and how), that her guest was not our guest?
