For two years, I had been the person beside my grandmother whenever life became difficult.

My mother was technically her daughter.

But somehow, I had become the one who showed up.

Every heart appointment.

Every blood test.

Every late-night phone call.

Every terrifying trip to the emergency room.

I knew which medications made Grandma dizzy. I knew how she liked her tea. I knew which television programs she pretended to hate but secretly watched every afternoon.
