Beside me, Caleb crushed his heavy paper coffee cup in his fist so hard that dark coffee spilled over his knuckles and ran down his wrist, and he did not seem to feel it at all.

His eyes were fixed on his mother.

I have never, before or since, seen Caleb that angry, and what struck me most was how quiet it was.

There was no shouting in him, no reddening face, no raised voice.

There was only that terrible stillness, the crushed cup, the unfelt coffee, the eyes locked on his mother with an expression I could not entirely read.

I knew my husband as one of the gentlest men alive, patient to a fault, slow to anger, forever making excuses for the people who did not deserve them.
