"Sunnie realizes she's a female, but she wants to do boy things," said Doris Thompson, Kahle's great-grandmother and legal guardian. "She wants to play rough and tough."
Thompson has raised Kahle since she was an infant. When she turned five, Thompson said she asked for a short hair cut.

"She had hair down to her waist and she wanted to give it to a child with cancer," said Thompson. "After we cut her hair she started wanting to wear jeans and a t-shirt. She didn't want to wear her frilly dresses anymore."

Her appearance started leading to awkward questions at school.

Kahle said her classmates would occasionally ask if she was a boy or a girl, but she said the question did not hurt her feelings.

The issue caught the attention of administrators at Timberlake Christian School, where Kahle was a student.

Elementary principal Becky Bowman sent home a letter last month, reminding Thompson of the school's religious affiliation and it's right to refuse students who contradict a "biblical lifestyle."

"We believe that unless Sunnie and her family clearly understand that God has made her female and her dress and behavior need to follow suit with her God-ordained identity, that TCS is not the best place for her future education," Bowman wrote in the letter, which was given to WDBJ7 by Thompson.
