Have you ever wondered what happens if a person hears that he/she is a disappointment too often? That he/she is useless?
What might happen is that this person might take on a behavior that tells the world to go screw itself. He/she might loose the will to make things right, to try to be good. Because why should you when you’re useless.
And if this happens with a recent disappointment in his/hers life it might even come with a lack of will to care. He/she might shut down completely and disappear, turn off the sound on her phone and only do what she absolutely have to.

Cheers to that.
