You don’t know what I’m going through, so don’t say that you understand and don’t pretend that you have been through something similar.
It is said that only a man with the same boots can understand why the other man is wearing them. Only a man who has been through pain understands what someone else is going through.
And when you lost your loved one to something very unfortunate, maybe you can sit with someone who lost their pet. When you break up with someone you loved with all your heart, maybe sit with someone whose family member went missing or someone who just got divorced. Maybe you can complement each other. You two might sit together and even though you cannot cheer up the other, you might be able to understand what it is like to be in their shoes.
You might not be able to tell someone what to do next, how can they get out of there, but just maybe be a listener and understand their condition. And sometimes, all someone needs is someone to understand their problem and realize what is going on in their heads with each passing second.
Sometimes, the way to get over some problem is not the solution, it is not the shoulder you cry on, but just sitting with someone who understands you.
