U,

Remember in school when you had the annoying kid who wanted to be your friend. He would show up at your house uninvited, call you all the time and you just wanted to be bothered. You would only call him when you wanted something. Then he finally gave up and started hanging out with other kids. Remember how you were mad at first mainly because it was unwanted attention but it was still attention. It had become your norm.

You didn't want the kid to comeback and be your best friend in entire world.
