Do you know someone who causes you a lot of frustration? Maybe you find them obnoxious or petty. Maybe their mere presence grates on you terribly. Maybe you have to work with them everyday, and just being around them makes you hate your job.
Or maybe you know someone who is smarter than you, or more attractive, or more charming, or who makes more money than you, or is more successful with the opposite sex (or their preferred sex, whatever that may be). Maybe the envy you feel towards them just eats away at you from the inside every time you’re around them, or even when you’re not.
Well, don’t worry about it… because one day they’ll be dead, and so will you!
