I'm missing my friend's Bridal Shower. What should I tell her?

Weddings are very stressful and tell her you are sorry for not making it to her shower because you didn't know the details and tell her the any of the bridesmaids would love to help in anyway they can as long as she asks in advance so they can fit it in their busy schedules. She has to realize everyone has jobs and other things going on and can't just drop everything for her with no notice. Sometimes brides get so caught up in the wedding planning they don't realize that and need a gentle reminder. Tell her that but be nice and she will understand.
