Nizam : our garden looks so messy. Do you have any idea to make it better?
Yudha : Hmmm. I intend to make a vertical garden from mineral bottles and hang the bottles on the wall. It will make the garden tidier and we are still able to accomodate Mom's hobby in gardening. Do you agree with it?
Nizam : I completely agree with your idea. How do we make it?
Yudha : I've searched from the Internet about it. We grow plants, such as small flowers or vegetables in the bottle, and we hang the bottles using wires on the wall. We just have to find many used mineral bottles as the pots.
Nizam : I think I know where to find the used mineral bottles.
Yudha : All right. You take care of the bottles, while I collect the seeds.
Nizam : No doubt about it, but I think Mom and Dad must know our plan.
Yudha : Yes. Let's tell them about it.
Nizam : O.K.
