I alway feel sleepy and tired after going off the office. The company assigned a task to me today. But it is impossible to finish on regular workday. So it is necessary to work overtime on weekend. I hate working on weekend, especially after 5 days of extremely hard working. I feel that I am so timid that no any defiance can be showed out. If you don't obey the order you will be fired. It is just like a feeble lamb. Only mastering oral and listening capability can it get out of this embarrassed situation.
