Mike was your average little boy. At age 3, he was happy and got along well with everybody. All that ended when his little sister, Jessica, was born. He always held a grudge against her for being the favorite child, but Jessica was always nice to him, which only further enraged Mike. Jessica was a precocious child. She started walking and talking well before Mike did, picked things up faster, and even beat her big brother on her first game of chess at age 7.

My sister took after our dad’s side of the family—tall, athletic, and naturally muscular. When we were in high school, a guy from a rival school tried to corner me after a football game because of some trash talk. Before I could even react, Chloe stepped right between us. She was a varsity rower and easily had three inches and twenty pounds on this guy. She just stared him down and said, 'Is there a problem here?' The guy took one look at her shoulders and walked away. It was humiliating for a second, but mostly, I just felt incredibly lucky to have her."
In that moment, I realized our roles had permanently evolved. I might always be the older sister chronologically, but she was the protector now. Story 3: The Ultimate Gym Partner
