hello! my cousin's wedding is coming up in Nov. My fiance and I received a save the date last Christmas when we met him and his finance for lunch. I didn't think much about not receiving an invitation until my father mention he received his almost three weeks ago. We already booked flights (had points that were expiring) and now I feel really awkward: I really want to ask about the invitation but I also don't want to be rude. Thoughts?
