Let me think about sarcasm:
Me calling the car garage: “My car does not work”
Garage: “What is the problem?”
Me: “Don’t know. It is not driving. You are the garage. Help me”
Garage: “Describe your problem”
Me: “Well, last year I could drive with it, now I can’t”
Garage: “Is it soo difficult to describe your problem?”
Me: “Are you getting sarcastic or are you trying to help?!?”
Off to search a cleaning cloth to polish my slightly dull crystal ball…
