2.
A blonde girl who is very lovable. She is extremely smart and athletic and has a wonderful ear for music. This girl has the ability to make anyone smile or laugh for as long as she wants to! She's also very beautiful and extremely stylish. Her friends love her for her ability to have fun and her sense of humor. Her nickname is probably Sig or Siggy, but I think she would prefer Sig.
Sigourney is so cool!
