She can't even sign her name, but is determined to give her daughter an education. Her husband doles out little more than physical abuse, but skimps to buy school supplies for her daughter. She sews together unused paper from her son's notebooks to make books for her daughter. She skips meals, so her daughter can eat.
She wants a better life for her daughter than she had. And she knows education is the only way to ensure it.
Her daughter knows it too. Which is why she wakes up before sunrise to finish all her chores before heading to school.
