This physical reversal has brought us closer. Without the shield of being the "stronger" one, our relationship has moved toward a genuine partnership. We laugh about the stares we get in public—people often assume she is the eldest, and we let them believe it. Her physical dominance hasn’t made her a bully; instead, it has given her a quiet confidence that I admire. She still looks to me for advice on life, and I look to her when I need something moved across the room.
We learn to appreciate our own strengths and weaknesses, and to be supportive and loving, even when things aren't always easy. We learn to let go of our jealousy and to focus on our own passions and interests. And we learn to value the unique gifts and talents that our sibling brings to the table.

One man shared his story on a forum, describing how he stopped growing at 14, standing 4 feet 10 inches.
