You named SOUND

Heart mumbling:

"The thing that u call sounds

Have double faces

One who turned both ends of your mouth upward

Another one, who turned both ends of your mouth downwards

Make its appearances

When someone closing the door

Or opening the door

It emphasize it can do a lot of tasks at once

By playing a band of musics

Circling my eardrum

When im trying to let go of my spirit

And jump into the call of rest by my creator

I rarely take a rest

When i did it, i do means that i really need to stay back a while,

Collecting energy

To continue my life tasks

That still left unfinished

You 

sound

Have the ability of healing

Also the ability of destroying

A sibling called 

mood"

Sound : "you need to be patient, because i am a test send by our creator"

Me: "o....k.... Bye......."  T_T redho
