Rage letters

A beat up.
All he can feel is pain all around.
Until he grabs an ankle.
Doesn't matter whom's.
He twists it, until he hears a click.
A body falling, screaming in pain.
The precious seconds he needs to stand up.
Breathing hurts, surely broken ribs.
Suddenly, he feels two arms grabbing him.
One around the chest, and the other around the neck, choking him.
He bites the arm that is trying to choke him.
Bites it hard.
Until it bleeds.
And when the blood reaches his tong, all goes crazy.
All goes black, white and red.
He is unable to think.
Just punch and kick and slap and bite.
No rules.
No first, second or third thoughts.
Like an animal.
Only the lust for violence.
Only rage.
No stopping until only one is standing.
Either he or another one, doesn´t matter.
He is fine with that.
And with a wild grin, he jumps to battle.
