A month had passed since Grandpa moved in/With the new family member in her home, Sara spent more time alone in her room working on her favorite hobby drawing 10 comic strips./She hardly showed these drawings to anyone.) Her parents thought it was a waste of time. They hoped she would spend more time on her schoolwork.)// Sara had been working for months on a 16-page comic book about a teenage girl with magic powers. She hoped to enter it in a comic book contest the next month but was struggling with how to draw the hero with invisible magic powers// One afternoon, she got so frustrated that she crushed almost all the pages she had drawn and threw them in the wastebasket) She didn't know why but her eyes were full of tears. //Her Her grandfather was moving She grabbed her jacket and went into the living room.
