So sad

I wonder what people say behind my back. I hear a lot of things that may apply to me when people talk about others behind their back, for example, when someone sees a girl with nappy hair and says, “Can she even get a comb through it?” I feel bad that I don’t say anything but I feel that even if I said anything they wouldn’t listen anyway. Is it wrong of me not to say anything? People are going to think what they want, even if I try to correct them this time. My words don’t have any power in high school and that saddens me.
