Your brother, Jason, had passed away, and your father was falling apart. Each night he went out as Batman got worse. Your eldest brother, the original Robin, didn't come home even once since.

"You can't be Robin, your brother just lost his life in that costume."

Your father argued. It made sense in some ways, but Batman needed a reason to return home every night - his Robin. You knew that you, as yourself alone, wouldn't be enough, you had years of being neglected to prove it.
