A goof ball and a half. She is adorable and funny. Very dedicated when it comes to her future. She is family oriented, artistic, and wants to really make you happy. She will give you her sweater if you were cold and more especially if your her significant others. She is loyal and crazy. This is a good combo if you know how to treat her when she’s feeling down in the dumps. Treat her with all the respect and she won’t let you down. A great friend and family member. I love her green eyes. *blush*
Her: “ I’m Dun-Nielle-ing at you “
Me: “ so originallol
