Mom was an extraordinarily clean person. After feeding my brother and me breakfast, she would scrub, mop, and dust everything. As we grew older, Mom made sure we did our part by keeping our rooms neat Outside, she would tend a small flower garden, which was the envy of the neighborhood. With Mom, everything she touched turned to gold. She didn’t believe in doing anything halfway. She often told us that we always had to do our best in whatever we did.

Never in good health as a child, Anita lost her hearing at ten. Her father’s business failed while she was in high school, so she quit school and found a job as a nurse’s assistant in a hospital for homeless people. Here Anita became interested in social welfare. At night she attended classes in composition and developed her writing skills. Soon she was writing newspaper articles. By thirty-five she had established herself as a writer. Although her life was difficult, she never gave up. In her nineties, she said in an interview, “Life is a wonderful teacher if we only listen to its lessons.”
