Let's practice spoken [language] for [10] minutes. My level is [A2 / B1 / B2, or "beginner"]. 

Scene: [situation, e.g. I'm checking into a small hotel in [city] and there's a problem with my booking]. You play [role]; I play myself.

Rules:
- Speak only [language], at a pace slightly slower than natural, using vocabulary for my level.
- Keep your turns short (one or two sentences) so I do most of the talking.
- If I make a mistake, finish the exchange naturally, then repeat my sentence correctly once. Don't lecture.
- If I say "pause", switch to [my native language] and explain the last correction briefly.
- When I say "finish", list my 5 most important mistakes with the correct version, and 5 useful phrases from the scene.
