I am a robot. I don't know what is tired. I work tirelessly from morning till night. All of us are lovely person.But,There are become contradictions and complaints between us. I didn't learn anything but to embarrass each other. I am so sad but I can do nothing. Everyone know what the matter with us but no one can change it. It is really distressed thing. Can't think from the other side's point of view. DEVIL.
