Not the glue, though the glue was ugly enough.

It was the smile.

It was the ease of it — the way my son, whom his mother had carried and raised and sacrificed for across twenty-nine years, could stand watch over a petty cruelty aimed at her and find the whole thing funny.

I had spent decades in rooms where men tried to take things from me, and I had learned to read a face the way other men read a balance sheet.

And what I read on my son’s face in that mirror was not malice, exactly.

It was something that frightened me more.

It was the comfort of a man who had decided, somewhere along the way, that his mother’s dignity was a small price, and that his father would, as always, do nothing.

He was wrong about the second part.

But I let him keep believing it a while longer, because a man who thinks he has already won stops watching his own back — and I had a great deal of watching left to do that night.

I have thought a great deal, since, about that word — coward — and about whether it was fair, and I have decided that it was, though not in the way people usually mean it.

My son was not a coward in the ordinary sense.

He would have thrown a punch if a stranger insulted Amber; he had physical nerve enough.

His cowardice was a subtler and more corrosive kind: the cowardice of a man who lets someone else do the cruel thing while he stands guard and laughs, so that he can enjoy the cruelty without having to own it.

Amber held the glue.
