The sound of his brother's voice, announcing his conversion to Rastafarianism, echoed in Mark’s ears. A wave of exhilaration flooded him. He felt as if a new door had opened.

He grinned. Reggae music, vibrant colours, perhaps a new outlook on life. The prospect filled him with warmth.

He began to whistle a lively tune as he rummaged in the fridge, looking for snacks. He knew this would be a time of celebration and expansion.

He ran over to his bookshelf and pulled out a book on Jamaica. He was excited to learn about his brother’s new life.
