What describes a feeling of "ennui" within a social context?

The concept of "ennui" relates to a feeling of dissatisfaction and boredom that arises from a lack of interest or engagement in one's surroundings, particularly in a social context. When one experiences ennui, it often manifests as restlessness due to an absence of stimulating activities or meaningful interactions. This sense of restlessness can be heightened when surrounded by others yet not feeling mentally or emotionally challenged.

In contrast, feelings of intense joy from social interactions reflect a positive engagement with others and a sense of fulfillment, while contentment with a routine implies a stable and satisfying lifestyle free of restlessness. The desire for solitude, while it may stem from feelings of ennui, does not encapsulate the core essence of the term, which is more focused on the lack of stimulation and boredom rather than a preference for being alone. Thus, the correct choice effectively captures the essence of ennui within a social context.
