Read the following excerpt from Gary Soto’s story "Like Mexicans."

My grandmother gave me bad advice and good advice when I was in my early teens. For the bad advice, she said that I should become a barber because they made good money and listened to the radio all day. “Honey, they don’t work como burros,” she would say every time I visited her. She made the sound of donkeys braying. “Like that, honey!” For the good advice, she said that I should marry a Mexican girl. “No Okies, hijo”—she would say— “Look, my son. He marry one and they fight every day about I don’t know what and I don’t know what.”
