Guess! Who Is He? Poem by Farah sherazi

Ssshhhh! ! ! ! ! Quiet,
He is coming,
The birds stop huming,
The wind stop blowing,
The sun stops glowing,
We all start moaning,
And............,
When he announces
The topic for today,
Are the complicated theorems,
Our smiles fades away,
So,
We go for a nap,
And get up after,
We feel a hard slap,
It seems another blast,
When he shouts and speaks fast,
It's him, It's really him,
It can't be anyone,
Except,
My....? ? ? teacher!
