Yesterday I had a bridal shower with my mom's family and someone my mom forgot from our guest list was invited. I don't know this woman at all, but I still feel horrible! All of the women around her were talking about getting together before the wedding and doing something and she sat their silent because she wasn't invited. So, now I want her to know she's welcome at the wedding and it was an accident. I am thinking about writing her a note along with the invitation. Would you recommend doing this and what would you say in the note?
