A kid was mad at his teacher for taking a test a day earlier than it was supposed to be (or so he thought), so he tweeted this...

Problem is, the test WAS scheduled for Tuesday and another student re-tweeted him and tagged the teacher on it...

So, what did the teacher do next day? He displayed the tweet nice and visibly in front of the class for the duration of class. The student was just quiet...

What would you have done in that situation?
