(CNN) The pep rally was underway as a South Carolina high school student headed to the bathroom. A teacher trailed him. The student is transgender, and she wanted to make sure he used "the right one," he said.
To him, the right one is the boys' bathroom, which he says he has used since seventh grade without incident. Then, in his senior year, school administrators told him he had to use the girls' restroom, he said. They also gave him the option to use the nurse's restroom.
When he exited the bathroom, the teacher did not say anything to him, but he knew f-rom the "exasperated" look on her face that he was in trouble.
The next morning, he was called into the vice principal's office said told he was suspended for one day for using the boys' bathroom.
