Explain, "The Love Song of Prufrock" as an Interior-Dramatic Monologue.

Again, this was answered before,

Basically it's a monologue where Elliot's speaker ruminates on his insecurities with women, his life choices, and general questions about life. He wonders if he did the right thing on specific occasions and muses about opportunities taken and missed,

“And time yet for a hundred indecisions, / And for a hundred visions and revisions, / Before the taking of toast and tea.”

Landscapes become a metaphor for his feelings and introspection spans themes in his life. That's basically the stuff of an Interior-Dramatic Monologue.
