Just called home to wish my sister a happy birthday . She was n't there , but after talking with my mom for ages I ' m now walking around the house trying to wash the English accent out of my mouth -- the one I had when I was 7 and literally lost years before leaving home , and yet rears it 's head every time I speak with my mother now . People usually hear a little something " off " in my voice and occasionally pin it to England , but not nearly as often as they used to .
According to the above context, choose the best option to answer the following question.
