We sent out our save-the-dates this week (our wedding party stuffed, sealed, and stamped them all for us) and my mom just called to tell me she got an empty envelope in the mail! We counted the left-overs and it looks like we may have sent out 5 empty envelopes. The return address stamp doesn't say our last names, so I'm super worried they went to distant relatives who won't know who it's from to let us know what happened.
Maybe someday I'll think it's funny?
