Criticism and Annoyance with Modal Perfects

• When expressing retrospective frustration, annoyance, or judgment about past actions, advanced English relies heavily on modal perfect structures. These forms allow speakers to convey that someone failed to meet expectations or acted inappropriately.

• Primary Function
• Example
• You might have + V3
• Expressing annoyance that someone failed to share information or take action
• You might have told me about the surprise party in Boston.
• Could at least have + V3
• Indicating the bare minimum expected action that was neglected
• He could at least have apologized profusely in Chicago.
• Should have known better
• Expressing self-reproach or criticism for foolish judgment
• She should have known better than to trust him in New York.
• Remember
• Use 'might have' to express annoyance over omissions.

• Use 'should have known better' to criticise poor judgment.
• Examples
• You might have told me regarding the sudden schedule change in Seattle.
• They could at least have called us before leaving Philadelphia.
• You should have known better than to invite her to Austin.
