The majority of tales center on a single, straightforward subject or occurrence. A brief, complete tale is what constitutes an anecdote.
Definition
A brief, complete tale is what constitutes an anecdote. Anecdotes can be factual or made up (or fall somewhere in the middle when it comes to embellishment), and the tone can be anything from grave advice to humorous commentary. The majority of tales, in contrast to other narratives, often concentrate solely on one individual.
Example
Imagine a mother and a father debating whether to have a family dog or not. The father remarks, "You know, my dog was my greatest buddy when I was a youngster." He made my upbringing a better one.
After giving his narrative, or his anecdote, some thought, the mother decides they should buy a dog.
