The Dialogue of Possibility (example)

One day in the school, Belva and Syafi are talking about their activities  on a Saturday night.
Belva : Hi Syafi, how are you ?
Syafi  : Hello Belva, i'm fine. And you ?
Belva : I'm very nice. What are you doing ?
Syafi  : I'm thinking about you. Hahay :D
Belva : Oh, so sweet.. 
By the way, what are you going the Saturday night ?
Syafi  : I don't know yet. I might not go anywhere. What about you ?
Belva : I might go to my grandfather's house. But maybe I just stay at home.
Syafi  : How about studying together at your home ?, if you don't go anywhere.
Belva : Ok, all right. I wait you in my home.
Syafi  : See you.
Belva : See you.
