Her name

She was like my sister. She was everything to me. It's been six years since I met her, But I've barely talked to her for three. I see her every day, But never say a word. But that doesn't make sense? That must sound absurd. I hear her name constantly, But it's not like when I met her. It's so much shorter now. It's only one letter. I see her every day. I have for six years. And even though we no longer speak, She still walks around with the name I gave her.
