People seem weak, but they’re strong. They seem strong, but they’re weak. No matter how much you cry, you still have to sleep. And you even get hungry. You suddenly realize you’re doing the same things you did yesterday. You say hi to your friends and smile just like you did yesterday. Life goes on as if nothing ever happened… I want to go somewhere… Anywhere… Somewhere where I can forget everything. …where I’ll forget everything …and be reborn. Mars Volume 18

The things that really shake the human soul aren't beauty or kindness. Although such things are certainly moving, but those feelings don't last long. But... anger or sadness are different. They leave an undelible mark. Even after the wound heals... you can never forget the pain completely.
