Then you should visit south europe. Europe is divided by the alps in a lot of things, like potato or tomato as main ingredient in meals. But also in culture itself. Everything north of the alps is kinda cold and seems unhappy/angry and stressed all the time and south of it people seem chill, happy and friendly.
I know you’re absolutely right but holding a grudge helped me with my depression and anxiety, cause then I didn’t feel the need to be the best around a person and that everything could be my mistake. No, there is a stupid person that I dislike and most likely it’s their fault!
