Ok I know you're not supposed to share a lot on facebook, but my mother posted our wedding date on facebook. My fiance's family doesn't know it yet, but they aren't connected to my mother so I don't think that will be an issue (he's supposed to tell her Saturday).
But we are likely only inviting 30-50 people, and a ton of people responded to her post that they are "looking forward to it"....but they aren't even remotely invited. Her library friends said they would make food for my shower on the post. I'm not inviting them! I'm not sure what to do with this
