helps svp pour le dialogues

J'ai souvenir que tu avais déjà poster une demande sur le même sujet. J'y avais répondu dans les commentaires mais apparemment tu ne l'as pas vu. Je te redonne le dialogue que je t'avais proposé. En espérant que ça ira.

D comme detective et W comme witness (=témoin).

D : Hello sir. Can you tell me your name?
W : Yes, my name is David.
D : What were you doing here tonight?
W : I had an appointment with a friend of mine, near there.
D : Alright, what did you see exactly?
W : I wanted to call my friend so I search my phone and then, I heard a loud shot! Someone escaped with a motorcycle. I was really scared, but I heard a guy calling for help. When I get there, he was on the ground trying to breath with his hand on his chest. I didn't know what to do.
W : So I called you and 911 (= urgences). After that, everything goes really fast.
D : Alright, I need you to come with me to testify what happened. Thank you for you help.

Cela est-il suffisant? N'hésite pas si tu as des questions. Bonne continuation!
