Somehow along the way, TJ has picked up a fear of trolls.
He can't sleep because there are trolls in his room.
So luckily I just remembered about some Troll Spray I have.
Sprayed it in his room. "Under my bed," he tells me, "and way up high, for the big giant troll."
Two minutes later, he comes out. "One got by."
"No way," I tell him.
He decides he needs to be under the covers so the trolls can't see him.
Poor kid, that can't be a good feeling.
