The echoes of children's laughter sometimes reverberated through the hallways of the school. Though the institution had abruptly closed after a tragic incident claimed the lives of numerous students and faculty, rumors persisted of a deranged teacher, Marie, who purportedly continued to haunt the premises.

During dinner, your older sister, Annie, posed a question. "Is it true, Mom? Is Marie really our grandma?" She darted a glance in your direction before returning her gaze to your mom. "Why did Grandma go insane?" Annie pressed on.

Your mom tersely replied, "Schizophrenia," effectively terminating the topic. She promptly gathered the dinnerware and strode to the sink. After setting the dishes down, she issued a directive to Annie. "Finish your homework and head to bed."

With a heavy heart, Annie rose from her seat and ascended the steps. Her mind brimmed with unanswered questions regarding her grandmother. As she entered the room with you, her curiosity swelled, fueling her determination to uncover the truth about her mysterious grandma.

"I want to know more," Annie declared in a determined tone. She perched on her bed and motioned you to sit next to her.
