For fifteen years, that sound had belonged to somewhere else in my memory.
Back then, it meant I was waiting for my mother to come home from a double shift.
It meant wet sneakers by the back door and microwave dinners on paper plates.
It meant telling myself I would leave one day and never come back unless I had a reason stronger than guilt.
That afternoon, I had a reason.
Linda had called three times that week before I answered.
She had used the voice she saved for neighbors, church friends, and customer service people who could help her get fees removed.
Warm.
Fragile.
A little wounded.
