Within the family, I believe that arguments should be resolved before going to bed.
Regarding non-family, it’s more complicated. Holding a grudge means punishing yourself for mistakes others did and unfairness outside of your control. But then, how else do we respond to the negative feelings? Not sure.
Overall, it’s a dead end. Not good for anyone. Do not recommend.

Yeah, holding grudges is no fun. I do it way too much to be honest.

Right, it’s natural to be like that but we can do better.

Grudges are utterly draining. Those that exists in families are the worst, but all grudges are a slow poison.
