Susan is having a bad day. She feels like everything she does is wrong and that she is worthless.
She just wants to curl up in a ball and hide from the world. She is so lost in her thoughts that she doesn’t even hear her best friend knock on her door.
When she finally comes out of her reverie, she sees that her friend has brought her a chocolate cake and a comforting hug.
With her friend’s support, Susan slowly starts to feel better and realizes that she is not as worthless as she thought.
