Hey! So, our wedding is one month way from today! RSVP have been coming and my FI, my mom, and I have been noticing this trend: people writing in plus ones when we clearly did not invite them (was not on the inner envelope). Apparently, these write ins are significant others, but we had no idea they were. I know you are supposed to include SO in weddings, regardless, but is it rude for them to write them in? Should they have called? We have ample space in our venue, but we are keeping it small because...well...we want to. FI and I both have large families, so we were not able to invite all the friends we wanted to (my parents are paying). What would you do, or should we do with these written in guest?
