Someone that RSVP'd yes is now not coming. Numbers are already in. A high school friend reached out to me today on Facebook. She has recently moved to the same city as me and wants to meet up. We were great friends in high school, but have lost touch over the years. Is it tacky to invite her to my wedding now? I do have an empty seat, we were good friends who lost touch...will it seem like I am just inviting her to fill that seat? Is there a way I can word it to let her know I'd like to rekindle our friendship? She will also be sitting with random people; there won't be space for her husband and the only other person she knows is at a full table already.
