Which of these is not an example of a phatic greeting?

A "phatic expression" is popularly known as small talk: the non-referential use of language to share feelings or establish a mood of sociability rather than to communicate information or ideas. The ritualized formulas of phatic communication (such as "Uh-huh" and "Have a nice day") are generally intended to attract the attention of the listener or prolong communication. Also known as "phatic speech", "phatic communion", "phatic language", "social tokens", and "chit-chat".

The term "phatic communion" was coined by British anthropologist Bronislaw Malinowski (1884 - 1942) in his essay "The Problem of Meaning in Primitive Languages," which appeared in 1923 in "The Meaning of Meaning" by C.K. Ogden (1889 - 1957), and I.A. Richards (1893 - 1979).

Examples:

"Hello".

"Nice to see you".

"Have a nice day"!

“Nice morning, huh”?

Non-verbal phatic expressions are used in nonverbal communication for emphasis or to add detail to the message that a person conveys or expresses. Common examples of these are smiling, gesturing, waving, etc.

Phatic expressions are used on different communication platforms on the internet such as social media networks where certain platforms require and prompt certain actions to be made between users to communicate or implicate certain messages between people without direct utterances. Examples of this would be; likes, comments/replies, shares/reblogs, emoji use, etc.

In short, “I need your report” is not a phatic greeting.
