A hit

A plain glass window of the quietest rooms 

Had been left locked for eternity. 

On hearing noises, found out a not so silent stranger, 

Knock knock, was all she did

Those staring eyes on a swaying head

Fearing a mighty thrust from the petite creature, 

I said 'I'm innocent'

But the pecker saw me more human

And went on pecking. 

Sharing some of that courage, 

I braved further, but she flew away.
