Why do you tend to be happy about knowing someone else’s failures? You also tend to have a pretend sympathy just so you could pass to be a “friend”. Is it really comforting to know that someone is having a bad life? Or the fact that you’re not the only one who’s failing is the real comfort here. Or you’re just plainly happy that you are already one step ahead of that someone.
Call it insecurity, jealousy, selfishness, but these traits are what make the world go round. People hate on other people for comfort. Look around, listen, and read between the lines. These kinds of negativity are very real in modern times.
