Today I get home from work and we have an RSVP that arrived from a relative of mine who lives in the same city where the wedding is going to be. Well I was excited to get another one in the mail, opened it up, and noticed she added an extra line onto what I had on there, 'will be attending' or 'unable to attend'....her extra line said "unsure" and she put a check next to it. Did I miss something? All other RSVP card examples i've seen didn't have this on it. The return date I have on it is September 15th, so she has plenty of time to send it in. This might be a common thing, but was just curious if I missed something when I created those RSVP cards?
