I just started a story where the author gave a lot of background. Like this:
Maria and Louis came from a small, poor town deep in Mexico. Their mother, once upon a time, had been a schoolteacher and her dream was to one-day see her children go to America, so they could have an opportunity she never had. She forced them to learn English from the age of six and made them speak it at home when no one else was around.
But a little later, I read this:
"How come you speak such good English?" Beckman asked the young Mexican girl.
"My mother taught me and my brother from the age of six. She wanted us to be prepared for when we came to America," the young girl answered.
Why did the author have to tell that info earlier? This would have worked just fine.
