What does it indicate when a person belies their feelings?

When a person belies their feelings, it indicates that they conceal or misrepresent their true emotions. The term "belie" means to show something to be false or to contradict. Therefore, when someone belies their feelings, they are not being truthful about their emotional state; instead, they may express something different from what they truly feel. This can manifest in various ways, such as using a cheerful tone while feeling sad inside or maintaining a calm demeanor despite experiencing anxiety. This choice accurately captures the essence of the term, as it aligns with the idea of hiding or masking one's authentic emotions.
