The document discusses different politeness strategies when making requests. The "say nothing approach" involves not directly asking and hoping the other person offers help. The "off record" strategy uses indirect hints rather than a direct request. The "bald on record" approach directly asks for something using commands. The "on record" strategy also directly asks but softens the request with politeness markers like "please" or question forms to reduce the chance of refusal. Direct commands are most likely to be refused while indirect hints are least likely, but direct requests can be appropriate in emergencies or certain social contexts.
