on Monday

Today, I couldn't work well. I know today

is Monday. But I was not affected by that. But today, I felt weak power and energy although yesterday I ate meat much. What is the reason?

As soon as arriving the office, I asked about last weekend's exam. But there's few people to take the exam. Mr. Lee said it was very easy. And Mr. Kim said it was not easy. Today, I tried to finish one function of my module. It was to delete a last created card. But it was more complex than I thought. Although I implement the logic, I found some bugs. Tomorrow, I will check that. Tomorrow is the last day of my boss being absent. So, I thought I just watched a movie and take a rest. But as there's some features that I should implement, I will focus on only my job. Time is going through middle of the last month. Can I do well?
