Internal and External Conflicts:

The internal conflict lies within the old man's struggle with loneliness and the search for meaning in his life. The external conflict arises from the contrast between the younger waiter's impatience and the older waiter's empathy towards the old man's situation.

Composition of the Story:

The story can be divided into the following parts:

a) The Exposition: Introduction of the characters and setting (the late-night cafe).

b) The Development: Dialogue between the waiters about the old man's situation and the younger waiter's impatience.

c) The Climax: The old man's request for another drink and the younger waiter's refusal to serve him.

d) The Denouement: The old man's departure and the older waiter's internal monologue reflecting on the human condition.

Stylistic Devices:

Hemingway employs various stylistic devices, including repetition ("nada" repeated several times in the older waiter's internal monologue), symbolism (the well-lighted cafe representing a sanctuary), and contrast (between the younger and older waiters' perspectives).

Conclusion: "A Clean Well Lighted Place" is a poignant exploration of existential loneliness, the human need for connection, and the contrast between youth and old age. Hemingway's understated yet powerful writing style effectively conveys the depth of human experience and the search for meaning in a seemingly meaningless world.
