Jealousy is a common feature. No matter whether a person is relative or a friend feeling jealous is a normal action. By being magnamious, you are only aggravating the situation. Jealous person will always will celebrate your downfall. In fact, he will not show his glee explicitly. On the contrary, he will " express" solidarity in the need of the hour. To me, these creatures are parasites so, it is always keep them at a distance. Next way to tackle them ......hmmmm...wait a while I will get back to you.. I know you are restless.
