What is the name of this short story?

The story is about a self-obsessed teenage girl who likes to flirt with men. She accidentally attracts the attention of this good looking guy who comes to her house to see her while her parents at her aunts (i think), but turns out to be an older guy. He uses different types of lingo showing that he has done this for many years. He never walks into her house until she tries to pick up the phone to call the police, and she ends up getting mentally broken down by him.
