Can you hold a grudge forever??

Never hold a grudge.... Grudge is like jealousy it eats in to a healthy oganism metaphorically like our hearts and minds...its rotten. I usually say there is two side to everything or there is a reason why someone behaviour is a certain way. for these reasons i dont hold a grudge, and for myself my life is too important to me to spend wasteful time and energy hating someone its not productive... I try to resolve it, but if it cant then so be it....once i forgive, i wipe the slate clean never to mention it again.
