Playtime in the "Hidy Hole"

There is a space under our stairs that my kids call the "hidy hole." I have no idea how this name came about. Chris and I call it the Harry Potter cupboard.
Nevertheless, this is one of Ronin's favorite places to play and bother his sister's. Too bad he doesn't know that he is bothering them. He just thinks they are funny or being mean for not letting him have a toy he wants.
