Ever since we have announced my engagement, my mother and sister have assumed that my sister will be the moh. The problem is she is flaky and all about her. I don't want her to be the maid of honor, it was just pushed on me. I don't want to hurt her feelings, but I want my future sister in law to stand next to me. Her and I are much closer and she is the one doing all the planning with me. How do I tell my sister?
