I'm officially a married woman (8/4/12)! Whoo hoo! My husband and I are in the process of starting thank you notes now that we've returned from our honeymoon. We have a hand full of guests that didn't give us anything at the wedding (no card, gift, etc.) and don't know what to do with these guests (one of these people includes my new sister-in-law!). Do we confront them or even send them a thank you for attending the day? I think it's pretty bold that someone would do this and have found it hurtful. Is there is proper way to let them know?
