We have a casual friend who, three weeks out from our wedding, is suddenly being very vocal (via Facebook and through mutual friends) about how excited she is for our wedding. She was inadvertently invited to the shower a couple months back, as she was on the "it would be nice" to invite list, and a shower invite went to her from my soon-to-be-MIL. She RSVP'd that she would be at the shower, and then failed to show up on the day of the shower and never said a word about it. Now, with less than three weeks to go, she has sent a gift and seems to be trying to score an invite. We are having a very small wedding- we made a policy to invite only those people we see and speak to on a regular basis. Do I need to invite this acquaintance? If not, how do we address this?
