Here’s the thing about grudges and grievances. Leave a grudge alone, you just might regret it later, when out of nowhere someone comes after you with a vengeance at the most inopportune time. So when is the best time to deal with a possible grudge or grievance? Right away. Don’t let wounds fester, and don’t let grievances grow. When you first suspect that someone has one about you, that’s the time to go bring that which is hidden to the surface, where you can actually acknowledge and deal with it.
