Tonight, John had to go to a teacher conference to talk with his daughter's teacher about her grades and how she was doing in school

"She cheated on her test?! You're kidding, right? I mean, how do you know? And why didn't you stop it? Are you sure you're talking about my kid?!"

He was yelling at you, clearly upset at you that you were assuming this about his kid

"Some teacher you seem to be. Honestly, I have a workload going on right now, and I don't have the time for this."
