Not everyone is the same

I feel that the school dress code policy is stupid because they have special excuses for others like people who are sick, injured, or are handicap are excused from P.E. and they can't excuse a for wearing a piercing?! Sitouations likes attack out of nowhere, like my sister was half suspened because she hardly had make up. So this means she could go to school for one half and the other half she had to go home. This caught my sister off her guard cause she never was aware of this and she missed half her lession just for make up?! I feel that schools are like prison were everyone wears the same clothes, eat the same food and are denied their rights. The school needs to try us, students, like individuals not criminals. I feel for the girl who just wants to learn, but is denied because of nose ring. It's her faith and it's not harming anyone. Some people even wear necklaces with the cross or virgin mary at the end of it. The school it's not fair, they should allow students to express their religion even if violates the dress code. Because it's messes up their education and makes them feel that their is not allowed.
