Oh my gosh, this sounds really cruel to write, but we do this all of the time. I hide in the darkened bedroom and Katie has to be brave and come in to find me. It's hysterical to watch because she's all twitchy knowing that I'll jump out and scare her. When I do, she high-tails it about 110 MPH out of the room. It's really funny and she goes into a zoomie afterward and looks like she's laughing, so there's no residual damage. It's all part of the game.
