Final answer:
The dialogue written is generally well-constructed, with a clear depiction of the characters' conversation and emotions. Minor adjustments for consistency in punctuation and capitalization are suggested, along with incorporating more descriptive details for depth.
Step-by-step explanation:
From the paragraph you've written, it appears that you have a good grasp of how to write dialogue. The conversation between the siblings in a late-night setting is clear, and the use of dialogue tags like "I quietly asked" and "Nisha said while yawning" help to set the scene and convey the characters' feelings. Also, the interaction is quite natural, with interruptions and emotional responses such as "I roll my eyes" and "Nisha exclaimed" that add to the authenticity of the speech. Keep in mind that when writing dialogue, consistency in punctuation and capitalization is important. For instance, ensure that you are using proper nouns such as "Nisha" and "Shivani" consistently with the correct capitalization. Additionally, consider adding more descriptive details or actions to enhance the dialogue, as seen in the examples you provided where the characters engage in activities such as feeling the wallpaper or talking to waiters, creating a more vivid scene.
