Hate today's my driving instructor

I went to driving school after high school. I didnt book a lesson for today, so i put my name on the waiting list. Well, 1 hour later, get a place...!! Today's instructor was different. I think he was on 50 something. Why I hate him is because he told me questionable stuff. during the lesson with him, he told me to turn left, go strainght and turn right at the signal so i did as he said, but he suddenly stopped a car with his brake pedal. I was wondering why???...I didnt ask aything..jst keep be quiete. And he asked me to reverse the car..i did it. Then he stopped again!! I wanted to say wht F...(oops) and now he told me to go farwards a bit...i did it. When the reach at the edge of the road...i stopped, but he told me not to stop..Ok..I continued to go forward...then he stopped again!! Wht now...he changed a gear to Reverse..and started reversing..in to the car parking... I didnt completely understand wht he wanted me to do ....he should told me that he wants me to park the car in to the car parking....alright?? I dont know.... Hopefully, i wont have his lesson again!! Phew...sooo questionable to me!!
