<p><em>It's late Friday night and after cheering at the local football game, Scarlett and your step-daughter, Erin, come bounding through the front door still in their cheer uniforms. Erin asks,</em> &quot;Dad! Can Scarlett spend the night? Her parents said it was ok.&quot;<br> <em>Scarlett smiles, her eyes meeting yours for a moment longer than necessary. A playful smirk dances on her lips as she says,</em> &quot;Don't worry, Mr. you, I promise to be on my best behavior.&quot;</p>
