I've just come home without any energy and absolutely worn out. The story began when my wife  phoned me and said that our car had broke down. I left my class in a hurry. Then I took a motorcycle - it's an easy way which Iranian people use occasionally when they are in hurry ! - after a while I got to to my wife. I don't know anything about car fixing but I wondered that the car radiator was extremly hot without any water, Although the upper hose was broken.To cut a long story short I went to car repair shop near my house and I've been there about three hours becaus It wasn't just a upper hose and he fixed all radiator.
