The most amazing girl you'll ever meet. She's smart, kind, and funny. She's very random and SO sweet. She has eyes that you could get lost in for hours and is very easy to fall in love with. She's a great friend, she's really loyal and caring, don't ever let a Kacy go! She's cool and everybody loves her. She's beautiful and all her friends tell her that, she just doesn't know yet.
Friend One: Oh my god! Who is that girl? I think I'm in love!
Friend Two: I know! She is SUCH a Kacy!

Cheerful girl. Laughs at almost everything. Gets her way, but not because she tries to. Only because people love her so much they just give it to her. Very pretty. All girls feel ugly around her. Everyone's first words when they see her is, "WOW SHE'S PRETTY!!" Most of the boys that meet her like her. She doesn't like being a heartbreaker. She hates ruining friendships. She's considerate, and sensitive. She'll always be there for you. She's trustworthy. You can tell her anything and she can comfort you. All in all, she is Honest, Trustworthy, Considerate, Sensitive, Pretty, Nice, and Funny.
