So one of my BMs who I go to school with texted me recently saying she wanted to put together a shower or brunch while we were at school, and asked who she should invite. As I'm already having a shower at home, and I'm not close with/inviting many people at school, I declined the offer. I recently found out via my fiance that she is planning a surprise brunch for me in a few weeks, and while i really do appreciate the gesture, two of the 5 people that will be there I am not very close with and are not invited to the wedding.
I hate the thought of people not invited to the wedding being at an event like this, even though it isn't a "gift giving" event like a shower, but I don't know if I'm just blowing it out of proportion. Is there a polite way to get out of it, even though its supposed to be a surprise, or am I better off just letting it happen?
