Days come and go but I must admit some of them are sad. And this is not because I am sad but those around me are too sad, too mad, way too busy with nothingness.
I cannot give any advice. In fact, giving an advice is such a hard thing… Not only you need experience, you also need power to say things out loud. And, so often people don’t need your honest opinion, they want you to validate their options. What can you do more? Just remain silent…
