Amelia O'brian is the best and the most beautiful human specimen you will ever see. She is perfect in every way you can think of although some of her friends say she isn't the smartest girl but she gets at least C grades on her reports which is still good. Her presence around you is the best feeling you will ever feel in your existence in your time on earth or in heaven which is the place she will go as her guardian angels will be preparing the palace for their queen. She has an amazing body and is great at sports, especially football(soccer) as every single human tells me when i talk to them about Amelia O'brian although i have not seen her play, i am 100% sure she will not disappoint you when you watch her play.
