I was a Kappa legacy. I grew up singing Kappa songs. I loved looking at my mother's badge and her old sorority pictures. I hoped to one day be a Kappa. I also grew up hearing that I should never be a Chi Omega! (Partly in jest as they were my mom's arch rival on her campus!) My school did not have a Kappa chapter. They did have a Chi O chapter. You can tell from my signature where I ended up! My mother was SO happy for me. (She still tells me to this day that all the girls in my house would have been Kappas at her school, though!

). We always make jokes to each other about which group is better, who has better alums, etc.
I do have to say though, I wish I could have shared the "special bond" of sisterhood with my mom. She and I are best friends, and no, we do NOT need sorority letters to make our bond any better, but I love my sorority and it's ritual and what it stands for and I would have loved for my mom to share it with me. Just like I am sure she thinks about her ritual and would love to have seen me go through it. I think it's more about sharing something you really love with someone you really love. Not about having a "better" relationship with your mom!
I have a niece now, and have already bought her a Chi O shirt before mom got her Kappa hands on her! And who knows if I will have a legacy someday. If I do, and she doesn't go Chi O, I'd love for her to be a Kappa!
