Your sibling isn’t the scoreboard. They’re the only other person who knows what that house was like.

Growing up in one house does not mean running the same race, though it feels that way when grades and sports keep getting compared out loud. Your sibling is the only other witness you get. They know what that kitchen was like at seven in the morning, and nobody you meet later will fully understand it. Ranking the two of you wastes the rarest thing you have.

Ask about something from back then and see whether their version matches yours. Say the thing you never say about your family to somebody who was in it. That conversation lasts longer than the competition stays interesting.
