Rossi replied because he has all the symptoms of classic narcissistic personality disorder.
The 9 tell tale characteristics of narcissism.....
[]An exaggerated or grandiose sense of self importance.
[]A preoccupation with fantasies of extraordinary success, power, beauty or love.
[]A belief that he/she is special and unique
[]An intense need for admiration.
[]A delusional sense of entitlement.
[]A tendency to exploit others without guilt and remorse.
[]An absence of meaningful empathy for others.
[]A tendency to be envious
[]An arrogant attitude.
That just about sums up Rossi in a nutshell.
I remember seeing an interview on TV in 2007.... an Australian female reporter asked Vale the following question at the PI 2007 round after talking about himself for the entire interview.....
So what do you think of Casey Stoner being the second youngest winner of a premiere class world title at 21 years old? (He was crowned world champ at the previous Motegi round)
His response: "I had won three world titles by that age".....which by the way was untrue as he won his 500cc title at age 22.
I lost much respect for him after that...... these days he is just a sad clown who rarely smiles.... to even respond to that tweet shows how much he is hurting and how much he values his place in the sport which also gives an insight as to why he and his fans are so pissed off by Stoners unarguably better stats....numbers dont lie (just ask NH).
