What might indicate a lack of etiquette in a situation?

Neglecting to introduce individuals can indicate a lack of etiquette because proper introductions are a fundamental aspect of social interactions, especially in formal settings. Failing to introduce people can lead to awkwardness and make individuals feel overlooked or unimportant. Introductions serve as a way to acknowledge each person in the conversation and can help facilitate communication. They create a welcoming environment and set the tone for positive interactions. In many cultures and contexts, neglecting introductions may be viewed as disrespectful, as it shows a disregard for social norms and the feelings of others.

Using casual language, while it may not be appropriate in every setting, could depend on the context and relationship between the individuals involved. Smiling when speaking typically conveys friendliness and openness, which are generally seen as positive traits. Offering a handshake is often a sign of respect and is commonly practiced as a greeting or farewell in many cultures, reinforcing proper etiquette rather than detracting from it.
