The Raven's tail

Remembering the past filled it with great pain
The Raven looked around at its tail
Looking through the window pane
The cheese that to get it would fail
Again and Again the Raven tried
But something it remembered it every time
Almost got in a pan and got fried
And then slipped into lime

The past, it could not forget
Friends, he had but they stabbed in the back
All the time, its mood was set
Friends reminded what did he lack
They annoyed him and taunted
Finally he realised he had to leave
As they wings, flaunted
So he finally did leave

It had been 2 weeks
Life had been better
He realised what one seeks
Is peace or one becomes bitter

Friends, he called them no more
Left them forever he had
As he saw a lion roar
He did not become sad
New friends, he had found, better than them
Who were like him, not idol and dumb
These new friends were like gems
And not at all dumb

This was his new life, he was glad he had
Better than the one he had

(How is it?)
