How can we define our jealousy? Maybe when we feel resentment towards a particular person or feeling desirous of having things we Don't? is considered that way .
It's something that could change our total behaviour towards that person, forcing us to resent him/her without our own acknowledgement. It could happen at any time towards any stranger or even our kins. We feel aggrieved, stars fantasising the "what is" . Obviously neglecting the preety things we have in hope of getting more.
Jealousy, can make years of love, years of bond into millions of scattered pieces. Though it's a disaster but as a human being , we are allowed to feel this way .
Something similar yet poles apart from jealousy is considered as 'Envious' . When we feel that 'I wish I could do this or overcome this situation like that person' . Or , 'Why can't I seem to have knowledge about these particular topics like that person'. It's kind of admiration.
Feeling I can be like that person , I can solve the problem like that individual is a sweet jealousy as long as it doesn't hurt the other party in any possible way .
Every time I feel this way about someone be it a person whome I barely know or my close ones , I ask myself, Jealousy ?? Maybe it's not .
