That's how the world works. Even if you are broken or confused or living in an illusion of happy world, you are always ready to help out people or just say feel the urge to understand people keeping yourself in their shoes. You ask me why?
Because that's how it functions. You may connect with everyone but feel only for one connection to decipher.
If I know how that feels when I was there in that situation ever, then how can I simply let the other person sulk or suffer alone. You know how that gets in your nerve, you know how that made you to suffer, then how can you expect me to not lend hand to hold, maybe ears to listen and eyes to see the hidden pain? Also the silence to understand your choas in a calm way of hope?
