Describing a person/character

My sister.

I have always seen my sister as my other half. We were born together, since we are twins. Firstly we seem very similar, but if people get to know us more deeply, we are exremely different from each other. Physically, she is blond and tall, but shorter than me, and she has the most beautiful blue eyes I have ever seen. Related to her personality, she is a very outgoing person, and she doesn't mind talking to people she doesn't know. She is also very nice, and her kindness is something I admire about her. Although we are always getting angry with each other, I love everything about her and I couldn't imagine my life without her.
