Her friend also has an older sister 20 months older than Nan. So clearly they are also bestfriends. Although it turns out the sister has a crush on J which was so funny. J told me he wanted to be lonely.
My daughter's best friend is blond just like her and born less than 24 hours after her. They are so silly and girly together. Sometimes they jump up and down screaming in glee at each other. Its quite humorous how silly and girly they can be.
