WELL then, BLESS HER HEART..If your niece is 6 (or younger) that is awesome. Level of Awesome drops for each extra year of age.
6 (or under): Awesome
7-10: She's sweet
11-14: That's nice
15-18: N/A because unless you are Justin Bieber (or equally vomitus) they don't know you exist right now.
19+ : Bless her heart.
