Don't worry about changing your relationship with your close friend even if she isn't your big sis. You already have a close friendship with her, so you don't need the big sis/lil sis relationship. This will give you both the opportunity to become close with other sisters in your chapter. If you really like to spend time together...Great! You are still sisters and can still do things together. The big/lil relationship is not meant to be the only relationship allowed between sisters in different pledge classes. Let your friend's little sis know that you are happy with your big sis and that you want to be friends with her too since you are such good friends with her big sis.
