My eight-year-old stopped talking, disappeared into the treehouse my late husband Josh had built, and came back down with strict new rules: boys-only, no questions. Then one night, I heard him whisper into the dark like someone was answering.

A month after my husband Josh died, our house still sounded like him. The hallway floorboard by the linen closet creaked under imagined boots, and the bathroom fan rattled like it was clearing its throat.

I kept catching myself listening for his keys, like grief could be fooled by routine.

Sean took it the hardest.

He was eight, and Josh had been his whole world. He stopped talking at breakfast and started picking at the skin around his nails until they bled. When I asked, “Do you want to talk about Dad?” he’d shrug and stare at his cereal like it had offended him.

Josh had built Sean a treehouse in the backyard right before he got sick. It wasn’t fancy, but it was solid—real wood, real nails, a little window cut out crooked because Josh said “character matters.”

After the funeral, Sean started disappearing up there every day.

At first, I let it happen.

If the treehouse helped him feel close to Josh, fine. I could live with splinters and dirt tracked into the kitchen. But Sean didn’t just sit up there.

He stayed.

I’d look out the window and see his sneakers on the ladder rungs, his skinny legs kicking as he climbed, and then he’d vanish behind the plywood door.

Sometimes it was an hour, sometimes three. Once, he carried a blanket and a pillow like he’d moved out.
