Bikin dialog? Kalo iya kira-kira kayak gini...
X: Good evening, can I talk to Y, please?
Y: Evening. This is Y speaking, who am I talking to?
X: Hey, I am X. I want to talk about our business trip next week. So, can you join?
Y: I'm very sorry that I can't. My mom is sick, she's in the treatment in the hospital now. By the way, I told my friend yesterday to replace me and he said he could. He will call you in a while.
X: Oh, okay then. I'm sorry for your mom, I hope your mom get well soon.
Y: It's okay. Thanks.
