I need help with a bridal shower quandry: my close friend is getting married in September, and I am a bridesmaid. Her 21-year-old sister is her maid of honor, and is in charge of planning her bridal shower and bachelorette party. A month ago, the MOH decided that the shower should be a secret/surprise for the bride. I cautioned her that a surprise shower would mean that we couldn't get the guest list from the bride, and risked missing inviting people. She ignored my advice, and created a Facebook event for the secret bridal shower, without consulting the bride on the guest list. The MOH then asked me to invite any friends of mine/the bride's that the MOH was not Facebook friends with, and I obliged.
Here's the problem: the MOH managed to get a peek at the wedding guest list, and two of my friends who have already RSVP'ed "yes" to the shower are NOT invited to the wedding. Now the MOH is demanding I explain to my friends that they will not be invited to the shower either.
I'm in an impossible position here. It could be awkward for these two friends to realize they aren't invited to the wedding, but they will definitely be upset if I revoke their bridal shower invite in addition. But what can I do? Alert the bride, ruin the surprise, and incur certain wrath from the MOH? Uninvite my friends and allow resentment to fester toward the bride who did NOTHING wrong? HELP!
