"Sis"

Nine times out of ten, when we are out and about the girls usually get along fantastically. When we are at parks, they especially have fun together. The other day, we were having an impromptu afternoon at the park. The girls were playing some silly game about alligators and having a great time. While they were playing, I noticed Adilyn was calling Kacy, "Sis." It was so cute for some reason! She kept saying, "Come here, Sis" and "Hurry, Sis!" It was adorable. When I asked her why she was calling her that, she said, "I don't know, I just like it." :)
