It started with two little girls wearing similar dresses. Then a family disagreement went too far. My mother’s reaction surprised me most.

“They are not twins,” Vanessa said.

The room went awkwardly quiet.

Vanessa was my older sister and Lily’s mother. For years, she had treated every compliment involving our daughters like a competition, especially if Emma received the same attention as Lily.

Mom usually encouraged it in smaller ways.

If both girls wanted the same toy, Emma was expected to surrender it because Lily had “seen it first.” If relatives brought identical gifts, Mom somehow found a reason Lily should choose hers first, and when Emma once wore a red coat similar to Lily’s, Vanessa accused me of copying her.
