Dr. Estella Jones and the Safari in Africa
Brightness controls whether someone sees the hopeful or dark side of a situation. Estella Jones had been living in the shadow of a threatening marriage and long odds for years, seeing the world through a lens of danger and constraint. The safari flipped something — watching animals live freely in a genuinely dangerous environment, she started reading her own situation differently. The danger was still there, but the possibility of freedom inside it came into focus in a way it hadn't before.
