Leena is a 7-year-old girl who comes from a community where gender identity is clearly defined. From early

childhood, Leena observed and mimicked the behaviors of her mother, sisters, and other female relatives, such as

playing with dolls and wearing dresses. Whenever Leena was witnessed mimicking these behaviors, she was praised

for being a "good girl" As Leena gets older, she continues to exhibit the same behaviors as her female relatives.
