Amy returned to her small apartment at midnight, exhausted. Pushing the key into the lock, she quietly opened the door so as not to wake her younger brothers. She stepped into the front room and froze. The apartment was a mess: plates of half-eaten food were scattered in front of the TV; toys littered the floor; clothes, shoes and homework were strewn everywhere. Amy’s eyes welled with tears. This is just way too much for me, she thought. Her worst fears began to race through her mind. Would the court(法院)tell her she couldn’t care for her family anymore? Would the kids go through the bitterness once more of being split up and sent away? She was so young, almost a child herself, and yet Amy knew everything depended on her. At that moment, she wondered if she would ever find the strength to see it through
Amy had been born dead. Doctors fought and saved this smaller twin of a drug-taking mother, and she’d had to fight for everything in life ever since. From earliest childhood, Amy took care of her younger brothers. Jan, their mother, only added to the family disorder and confusion. Sometimes they lived in apartments, sometimes in shelters.
