On the first day at my new school, my teacher, Miss Soria, gave me a sticker that said René Colato. The sticker was missing my second last name. Maybe Miss Soria's pen ran out of ink. I took my pencil and added it. Now it looked right: René Colato Laínez. Young René is from El Salvador, and he doesn't understand why his name has to be different in the United States. So when the students are given a project to create a family tree, René is determined to explain the importance of using both of his last names.
