When introducing two people who are well acquainted, how can you make the introduction?

Making a casual introduction using first names is appropriate when the two people being introduced are already well acquainted. This approach reflects familiarity and comfort in their relationship, suggesting that they can engage with each other on a personal level rather than needing to adhere to formal etiquette. Since both individuals already know each other, the use of first names helps to reinforce their existing connection and allows for a more relaxed atmosphere.

In contrast, formal introductions with titles are typically reserved for situations where the individuals are not familiar with one another or when the social context requires a level of formality. Using titles alone or last names can create unnecessary distance and may not be suitable when the parties already share a rapport. Therefore, using first names strikes the right balance in this scenario, enhancing the warmth of the interaction.
