Trouble with his best friend

I used to think,
That he was nice,
In a funny sort of way,
He was my friend's world,
And she was his,
But that was another day,
Today they made each other cry,
By one filthy lie,
That was not their's,
That stayed,
Unrecognised,
It was so cleverly,
Disguised,
That they blame,
Their true love,
When,
It,
Wasn't,
Even,
Their,
Fault,
It was his best friend that did the crime,
After being rejected from time to time,
A rat face,
A rat race,
To get a girl,
But he is short,
In size and thought,
Rat like,
Thinks he's psy - schic,
He's not,
As hot,
As loveable,
As he thought,
He's a jealous swine,
The best friend betrayer this time isn't mine,
Says he dumped her,
She swore,
Thought more,
Of the liar,
Had fire,
Raging in her eyes,
All lies, all lies,
Of course,
There's remorse,
Not to him,
He does not know,
How low,
Can a friend,
Sink?
