"I've had the same color for the past three years, and nobody at school has commented on it." ...sort of gives it away.
True. The thing to me is , Why after 3 years is this suddenly an expelling offense? Me thinks there’s a muzzy on the school board.
Actually no it doesn’t. What she is saying is that she spent the last three years in that school and no one every said anything about the color of her hair. She is not saying that she has been dying her hair for the last 3 years.
