Scene: Inside a university library study hall.
(The scene opens with DAVID sitting at a desk, then suddenly falling to the floor. SARAH gasps and kneels beside him.)
SARAH: David! David, are you okay?! He's not **responding**!
(Sarah grabs her phone and dials quickly.)
SARAH: Please, please pick up!
OPERATOR: 911 Emergency. What's your emergency?
SARAH: Hi! My friend has **collapsed** and isn't responding! He's **breathing**, but he won't wake up!
OPERATOR: Okay, ma'am, stay calm. Tell me your exact location.
SARAH: We're on the third floor of the university library, near the history section!
OPERATOR: Thank you. I have **paramedics** on the way. Now, can you tell me what happened? Did he complain about anything before he collapsed?
SARAH: No, nothing. We were just studying, and then he suddenly fell out of his chair. He was fine one minute ago!
OPERATOR: I understand. Listen carefully: I need you to check his breathing again. Look at his chest to see if it's rising and falling.
SARAH: It is. It’s slow, but he's breathing.
OPERATOR: Good. Now, please put him on his side to make sure he doesn't **choke**. Can you do that?
SARAH: Yes, I can. (Struggling a bit) Okay, he’s on his side now.
OPERATOR: Excellent. Stay on the line with me. The paramedics will be there very soon. Do not **hang up**. Just try to keep him as comfortable as possible.
SARAH: Okay. Thank you so much!
(Sarah stays on the phone, looking down at her friend as the sound of sirens grows louder.)
