My fiance and I are paying 100% of our wedding. Our initial guest list roared up to a whopping 360 people, so we decided to cut down. We changed our plans and decided to do an intimate Lake Tahoe Wedding with 60 guests. About two weeks ago, my mom called to tell me she invited a couple who are friends of hers - I've known them since I was four, but haven't seen them for at least 5 years. I explained that our guest limit is59 people and we are almost at our limit. Yesterday I got an email from her with the address of another couple who she wants us to invite. How can I make her understand?
