Helpful.

The kind of man who volunteered to assemble school furniture and remembered which cereal Ethan liked.

Ethan stopped asking friends to sleep over.

Marcus said he was becoming independent.

He flinched when someone raised a hand too quickly.

I told myself grief could do strange things to a child.

That is one of the hardest truths I have ever admitted.

I was a physician trained to recognize danger in strangers.
