The phrase "crying a river" is often used to describe someone who is crying intensely or for a prolonged period. However, its antonyms suggest a range of different emotions and reactions. For example, someone who is "stoic" or "unemotional" may not show any outward signs of sadness or distress. Conversely, someone who is "laughing" or "celebrating" is likely experiencing positive emotions. An individual who is "content" or "at peace" may feel a sense of calm or acceptance rather than crying. Other antonyms for "crying a river" could include "composed," "happy," "dry-eyed," or "indifferent," depending on the context and situation.
