TASK 5: THE MAN NEED TO FINISH THE PAPER TONIGHT BUT HE HAS BEEN INVITED TO A CONCERT AT THE SAME TIME

The man has a paper due tomorrow, and he hasn’t finish it yet. Nevertheless, his friend has invited him to a concert, and they have already bought the ticket. Moreover, the fee of the tickets are on his friend. He could work on the paper after the concert, but it would be a bit tiring to stay up late, and he cannot assure the quality of the paper. He could also choose to call off the plan with his friend, but he is afraid that his friend may be really disappointed.
