He had chosen his moment.

A three-year-old, in the middle of the most overwhelming and confusing day of his short life, had held a life-or-death task in his mind and carried it out with a steadiness that half the adults I know could not have managed.

We talk about courage as though it belongs to soldiers and firefighters, to the large and the strong.

But the bravest thing I have ever personally witnessed was a very small boy in an oversized suit keeping a flash drive secret from a monster, because his mother had asked him to, and he loved her, and he understood — in whatever way a three-year-old understands anything — that it mattered more than being scared.

He saved us.
