I'm really sorry to cancel our date, and I didn't have the time to explain to you yesterday. I'm sorry. I really plan to go home this week, but, tonnes of work waiting for me to complete here. And the main reason that make me stay here is due to the mid term on Monday is one of the tough subject of mechanical and I had been skipping the lecture for the whole chapter. I got to find some ways to catch back what have I missed.
Really sorry to disappoint you. I hope you can forgive me. And I wish we can meet as soon as possible.
