Evan: "Ethan, brother, it's Sunday today and I need some notes."
Ethan: "Don't worry, little brother, I'll ask Ava to send you the notes. She has all the notes."
Evan: "I need them today because I have to study today."
Ethan: "Okay, I'll tell Ava to send you the notes. She has all the notes."
Evan: "Okay, brother, tell her now. Call her."
Ethan: "Okay, I'm calling her now."
After a while, Ethan calls Ava.
Ethan: "Hi Ava, how are you?"
Ava: "I'm fine, what about you?"
Ethan: "I'm fine too. I need some notes, can you send them to me?"
Ava: "Sure, how many notes do you need?"
Ethan: "..."
Ethan: "I don't know, let me ask Evan." (to Evan) "How many notes do you need, brother?"
Evan: "Five, brother."
Ethan: "Okay, got it. (to Ava) She needs five notes."
Ava: "Okay, I'll give them to her when I come to the university tomorrow."
Ethan: "No, no, can you send the pictures (of the notes) instead?"
Ava: "Yes, I can do that."
Ethan: "Then send the pictures, please."
Ava: "Okay."
After a while, they start having snacks.
