This afternoon I was hit over the head by a hammer. I was on my hands and knees, picking up bits of plaster, and shoved aside the ladder I’d left it resting on top of. When it fell, it felt just the way I always imagined it would. I was stunned. Now there’s a bleeding lump the size of a small egg on the top of my head. It’s what a cartoon character would have, only it’s me.
