JEALOUSY-JEALOUS
synonyms: envy, covet

The feeling people get when they cant be like you! They wish they had your looks, talent and material possessions but they don't.. so they badmouth you instead to level the playing field. When they do this they usually don't tell the truth about anything either. Theres a difference between plain jealousy and constructive criticism.

a person becomes jealous because they perceive someone else as having or being something they don't believe they think they can have or be, so they feel that they are inadequate, that is why they become angry with that individual and try either conspicuously or inconspicuously to sabotage them because they are trying to take something away from them, to feel equal to them.

the reason why girls talk shit

A feeling of unhappiness that someone else appears better off than us.

A completely natural human emotion which we all experience and which is only villified because of the haves continued attempt to maintain their position over the have nots. Let me explain:

Back in History:
Haves want to keep what they got Have nots want it. More Have nots than Haves so Haves in danger of facing rebellion.
Solution? Use their power over people minds through their control of religion (its a fact that rulling classes control religion for their own ends- think how the mediaeval abbots managed to get so rich and divine rights of king etc.) to make it seem as though wanting what you haven't got is evil. Therefore Have Nots believe them and stop wanting therefore no rebellion therefore Haves get to keep wealth.
In The present:
Less people religious but this universal belief of religions deeply inbedded in human psyche so most people still think its wrong to show natural Jealousy.
