Antithecal alphabet

For each letter of the alphabet write two opposing alliterative attributes. They can be attributes for a person -- and might spark an intriguing character -- or for an object -- which might spark a story idea or add to the atmosphere of a scene.

For example:

• zany and zombielike
  
• yakkity and yawning
  
• exhibitionistic and xenophobic
  
• wacky and well-balanced

(A surprisingly common technique to fall asleep is to create a list of things from A to Z, like animals, diseases, countries. Maybe this prompt can be recycled as a sleep aid!)
