I was about to make my driving license (the theory part) and didn't knew the date for it - i forgot it completely. So i randomly walk in the school to ask the teacher and he says: "so, you think you can manage this, you learned well?" I say yes and ask him when it starts. Instead of answering, he hands me a exam sheet, which i assume as a copy of the official exam paper, saying, ""Let's see."
No sweat, i think, he wants to check my learning level, so i fill it with two errors, what was okay.
After that, i hand him the sheet back, he checks it. So i ask again, when was the official date for the exam? He gives me a hand to shake and says: "Congratulations."
Could you imagine my face expression at that moment? "Thank you...?"
(I'm sorry, did i just passed my exam and didn't even notice that i was doing it, Mr. Teacher?)
