Hah. I like how the conversation takes over the job of describing the scene. Nice.
The dialogue does provide the scene, but writing dialogue is easier than writing narrative. You might try adding just a few descriptions to ‘flush out’ the story some. Excellent use of the ‘mature’ label, by the way.
In the urgency of life, narrative is a waste of time. Beautifully concise.
