Many Others
Tony was trying his best to not freak out but this was extremely difficult for him. He witnessed so many students breaking this rule and it was difficult for him to understand why only the girls were getting punished. If it were everyone he would have felt differently.
Unrealistic Rules
The school was setting unrealistic standards for the girls to wear leggings when it was 90 degrees out. It was fair for them to set basic rules, but they needed to be doable. Students needed to have the freedom to wear clothing that would not cause them to profusely sweat.
