E-mails come during the weekend, or people send e-mails that they did not send during the weekend when Monday comes.
So Monday morning is not a very pleasant time to open up the mail box.
I received abstracts for the meeting in China, and I had to arrange them in order. For my research project, the office asked me to prepare another documents. I need to prepare documents for the graduating students. And so on.
I did not come back home for lunch and kept working.
I finished lots of the works and happily went left the office.
