Sadness, is best of me

Sadness
Sadness

Oh i am so sad
Because i smile while i do not want to do it

I should be happy
But they all sad when i just put smile on my face

They scary at me, but
They scared me to much

They say i am strange
I see they are stranger when they push me down to the corner of the box

Here is the box
I am under the table
I scary
They are hiding

Oh my bad, 
They saw a knife in my back last night
I am so sorry
You beat me down
I save the knife
Not mine
I stolen it from your pocket

I am a best learner
I am best downer
I am plagiator
I am a best i am.

Best of me, only
Sadness
Sadness
