My 8-year-old son suddenly began sleeping on the floor outside Grandma’s bedroom every night. I didn’t understand why until 4 a.m., when I heard him whisper through the darkness, “I won’t let Uncle do that to Grandma again.

“He came back once when you were asleep.”

I stared at him.

“What?”

“He used his key.”

“Why didn’t you wake me?”

Tyler wiped his face with the edge of his blanket. His answer hit me harder than I expected because it forced me to remember the conversation I had dismissed only days earlier.
