I lead Paco through the house. We pass Shelley in the family room looking at some magazine. "Shelley, this is Paco. He's Alex's friend. Paco, this is my sister, Shelley."<br />At the mention of Alex's name, Shelley gives a happy squeal.<br />"Hey, Shelley," Paco says.<br />Shelley smiles wide.<br />"Shell-bell, I need you to do me a favor." Shelley bobs her head in response as I whisper, "I need you to keep Mom occupied while I talk to Paco."<br />Shelley grins, and I know my sister will come through for me.
