AITAH for laughing in my SIL’s face when she DNA tested my daughter?

In a heartbeat, a man’s life was forever changed—not by blood, but by unwavering love. When tragedy struck and took away the lives of his childhood friend and her husband, he found himself standing at a crossroads with a fragile newborn in his arms. Though no biological bond tied them, his heart chose family beyond genetics, embracing the daughter left behind as his own.

Faced with the daunting unknown of fatherhood, he stepped into a role many would shy away from, driven by a fierce determination to honor the memory of those lost and protect the little girl who deserved more than a cold foster system. His story is a testament to the power of chosen love and the profound strength found in unexpected responsibility.
