You've met people like the Great Hagges. Broad in the beam, determined and strident, they subdue petty officials with a single look and ensure everything around them is neat and tidy and well-planned. They're often to be found in the caring professions, but don't be fooled: they are not kind, or gentle, or sensitive to other people's feelings - not even the teeniest little bit. They just don't like mess.
