Description of a person- Compulsory post

I know my best friend since I was three years old. She has long blond hair. When she was a child, she used to say that her hair was like a horse's one. She was deeply obsessed with horses and now she practices horse-riding. She is an average person, she is slim and she has tanned skin. She is my best friend because we have lots of things in common. For example, she was born four days before me and our fathers are named in the same way. That moment I have just remembered is when she told me that she could have to go away from Murcia to study Medicine, which was what she wanted. It was a bad memory because I cannot live without her, I look on her as my sister. Fortunatelly, for me, not for her, she could not access to that degree, thus now she is studying veterinary science and she is still very close to me. I need her due to her loyalty and joyfulness. She looks like me. I am afraid of losing her and I do not want her to forget me. If someday we have to be apart from each other, I do not know what I am going to do.
