Sheldon Caldwell was, under normal circumstances, a fairly gentle older brother to Susan Caldwell. Their relationship wasn't particularly close, but he still fulfilled his brotherly duties and generally took care of her.
Consequently, Susan Caldwell wasn't usually afraid of Sheldon Caldwell. She had heard from others about how exceptional he was and knew he was an outstanding soldier, so when she saw him today, she was secretly delighted. She thought he would surely give her special treatment during this military training and let her off easy.
However, reality dealt her a harsh slap in the face.
Her dear brother was the very definition of impartial today.
She didn't dare try to leverage their relationship anymore, nor did she dare call him "Brother" to his face. She was afraid he would really punish her according to the strictest standards.
She bit her lip and said unwillingly, "Yes, sir!"
