Hallo guys... Saya ada tugas bikin dialog expression surprise untuk 4 orang. Susah banget bikinnya, tolong bantu saya yaa...

(Zufar is in front of class. He waiting for Elsy. And then, Elsy come out from the class)
Zufar : Hi! Elsy!
Elsy : Hi! What are you doing?
Zufar : Nothing. I just want to go to canteen. Do want to go to canteen with me?
Elsy : Ok. Let's go.
(They walk together, Zufar turns his head. Emon and Ara give such code to Zufar from the class without Elsy know what happens. And they arrive at canteen)
Zufar : Oh God! I forget to bring my money.
Elsy : You can take my money.
Zufar : No, no. Come on, we have to go back to classroom.
Elsy : Ok, it's up to you.
(Zufar and Elsy run back to the class. Zufar enter the class. But, when Elsy enter to the class too....)
Zufar, Emon, Ekin : Surprise! Happy birthday, Elsy!
(There are many balloons, a birthday cake, and some gifts from her friends)
Elsy : What the hell is going on?
Zufar : Are you forget this day, Elsy?
Emon : Yeah, it's December 20th.
Ara : It's your 16th birthday!
Elsy : Oh God, how can I forget this day?

Elsy : Oh, Zufar, thank you. It's very surprising!
