One of the frequent questions asked by students of psychology is: "Please
explain the connection between Provocations, Irritation,
Aggravation and Frustration?"

The following explains it:

One day Parvez Musharraf, who has a business of selling iron rods, was
Sitting in office and got a call from Vajpayee;
Vajpayee: "SARIYA (iron rod) HAI Kya?"
Parvez: "HAI."
Vajpayee: "PEECHE GHUSA LE (shove it up)" and then he disconnected the call.
This is Provocation!

Again on the next day Parvez got a call;
Vajpayee: "SARIYA HAI?"
Parvez (trying to be smart): "NAHI HAI"
Vajpayee: "PEECHE GHUSA DIA KYA?" and then he disconnected the call.
This is Irritation!

On the third day again Parvez got the call; Vajpayee : "SARIYA HAI?"
Parvez (trying to be over-smart): "HAI BHI OUR NAHI BHI"
Vajpayee: "ANDAR BAAHAR KAR RAHA HAI KYA?!!!!" and he disconnects the call..
This is Aggravation!

The next day Parvez thinks of taking revenge... so he calls up Atal
Bihari.
Parvez: "SARIYA HAI?"
Vajpayee: "KYON? PEECHE DALNA HAI KYA?"!!!!!
This is Frustration..
