Friendly Address Privileges

"Dominic Greene: My friends call me Dominic.

James Bond: I'm sure they do."

- Quantum of Solace

When a character wants to make things a little less formal, perhaps to show how amicable and gracious he is, or just because he's laid back and being friendly, he might decide to drop the formalities and invite others to use his first name, or even a nickname.

A common Subversion is for the other character to then pointedly abstain from using the more casual name, or for the first character to specify that while his friends call him that, the character they are talking to shouldn't.

A subtrope of Don't Call Me "Sir"!. When subverted, often overlaps with They Call Me Mr. Tibbs.
