The fourth book in the popular ‘Lessons of a LAC’ series, Grey-glasses-itis helps children to understand the link between how they see things and how they feel. Loppy notices that he feels differently when he looks at the world around him through different-coloured glasses. When he’s using green glasses, he feels relaxed. When he’s using yellow glasses, he feels cheerful. But when he’s using grey glasses, he just feels sad. As his friend Curly explains, he has a case of ‘grey-glasses-itis’! Curly shows Loppy that to feel better he can change the colour of the glasses he’s seeing things through. This is a simple but effective way to explain to children how thoughts, perceptions and feelings influence each other. They will grow up knowing that when they are feeling sad, worried or angry, it might be because they have a case of ‘grey-glasses-itis’. They’ll also know that with a shift in perception they can have some influence over their feelings, thereby helping to build their emotional resilience.
