This is a classic what NOT to do...just received a college roommates wedding invitation. Just a single flat card invitation. No RSVP card, no RSVP instructions on invites..nothing...not even an insert or line that includes a wedding website for an online rsvp option.
At first I thought, well maybe she forgot it in mine--or intentionally left it out to be petty...(we had a fallout in college, but have since been amicable when around each other. Also, I did not invite her to our wedding, since we had a smaller guest list) but after chatting with a few other college friends (one who is in her bridal party)- it is clear that she did not include rsvp's for anyone. Her BM estimates that about 300 people have been invited--mostly from her (and her FH's) small hometown, and she thinks she will hear back by word of mouth from enough people to get an idea of a headcount.... this does not surprise me at all from her...BUT people please don't think this is a good idea!!
