A prevaricator
Father: this time you have to show me the best result. I am tired of hearing your worse result and I don't want it to be retrogressive anymore.
Son: No baba, I have studied a lot this time and I won't be failed. It seems like I will secure first position in the class.
The son with a pretending behavior failed in two subjects came over and congratulated his father on his success. The father welcomed him with the core of his heart and presented him with a cart as a reward.
