Why do people hate to see others happy?

Damn QotD you got real, real fuckin quick lol
Well I see it as people's inability to look past their own desires. When you get so caught up in yourself, you can't handle when others are happy. I've seen it in the past a hundred times, and I doubt I'll never see it happen again. Best advice ever is to focus on bettering yourself, because when you're focused on being the best you, you don't have time to pine over what others "have" 😊
