A sister.

In a world so vast and wide, I searched for someone to confide. Then you came, my guiding light, A sister by my side, day and night. Through laughter and tears we've shared, A bond so strong, it can't be compared. You understand me like no other, My sister from a different mother. In times of joy or times of strife, You're the one who brings balance to my life. With you, I feel complete and whole, My sister, the keeper of my soul.
