By Lupita's own description, she has an ideal mother. Mariana the mail carrier is strong, brave, wise, kind, a good cook, and above all, fun. She paints Lupita's sleeping alcove ""all orange,"" kisses her hurts away, loves to take her on outings, and even listens to the troubles of the lonely people on her route. And just to show she's human, Lupita's mother does get angry if Lupita leaves crayons on the floor or if a stranger berates her for ""taking a man's job away."" But mostly, as projected here and pictured in McCrady's free-and-easy drawings, she's happy--and so is her energetic daughter. And that's all: the pictures set a relaxed cheerful tone for a story and so does the text, but where's the story? Perhaps that's too much to ask of so transparently pragmatic a project; and, with its lighter touch and its continguous Spanish and English texts, this will have its uses.
