This person is absolutely amazing. May come off as shy at first, but she is anything but that. She has gorgeous eyes and stunning hair but her personality is what will capture your heart. She is smart, caring, beautiful, hilarious, crazy, random, nice and is a great friend. You are one lucky person if you have a Mary Kathryn in your life! Don't ever let her go!
Mary Kathryn is amazing!

Some one who takes real friends who are looking out for her best interests for granted.
Mary Kathryn is a real BITCH.
