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."At the mention of Alex's name, Shelley gives a happy squeal."Hey, Shelley," Paco says.Shelley smiles wide."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."Shelley grins, and I know my sister will come through for me.
