There was a girl. Why was there a girl? Who knows. This girl was the best girl in the world, in fact, she didn't know it, but someone had arranged it so that the world would be perfectly made for her. The letter to her was lost en route. She wasn't told.
The one who had created the world and the girl, also made one other. This other's job was to show the girl that the world was made for her, including him.
The boy wasn't so good at his job. Every time he got near to the girl, he got very nervous, and so couldn't show her. Once, though, he did show her. She didn't realize what he was showing her, but she got the first stirrings of it.
The boy thought that that was great. He thought that she was great.
He thought that she must be the smartest, kindest, nicest person he had ever met, and she was. But she didn't know that either, so he took it upon himself to let her know. So now he had two jobs to do…but he didn't mind, he loved it. He loved her, but sometimes, when she didn't get the hint, he felt sad. Sometimes, also, she got the hint, but rejected it, this made him feel even worse.
None of this was her fault, it was his. Sometimes he didn't give the hint right, and sometimes he didn't give it at all, but she got it anyways.
Now, the boy needed the girls help, so he wrote a fictional essay to her that represented all of this.
Would the girl understand now? If she didn't, it would only make things worse.
And how would he give her the message. Well, this is how he gave her the message:

Kelly, You are the single
Smartest, Kindest, Nicest, most Beautiful person that I have ever met!

Understand?
