losing her memory

Alivia, a girl with a lot of friends. She was walking on the sidewalk on her way to school, when a truck came around the corner and was driving on the sidewalk. She had headphones on so she couldn't hear it. when she noticed it, she didn't have time to get out of the way. next thing she knew she was waking up in the hospital. She saw 6 people staring at her. They were all crying and hugging her, while she had no emotion on her face. "Alivia what's wrong?" one asked. what she said next none of them could understand what she was talking about. "Do I.........know you?" Alivia didn't remember anyone. None of her family or friends. But she remembered 2 people. Her grandma shiela, and 1 kid from her school.
