For some, the physical change even leads to a newfound sense of protectiveness and care. A brother who felt quite happy about his younger sister's size admitted that he "sort of enjoy[s] it when she lifts me up or shows off that she is taller." His sister loves carrying him around, and the interaction becomes a form of bonding rather than a power struggle.

In an unexpected twist, her physical disadvantage became an advantage.
Our family went camping, and Chloe spent the entire three months eating everything in sight and sleeping fourteen hours a day. By September, the transformation was staggering.

Mark (22, 5’11”) had always been the scrappy older brother. He taught his sister Leah (19, 6’2”, 170 lbs of college swimmer muscle) how to throw a punch.

At 5'8" and an athletic 130 pounds, she was nearly a foot taller and 30 pounds heavier than her brother. One night, when a strange noise came from the backyard, their parents automatically sent Chloe to investigate while Alex, the older brother, was told to stay put in his room.
