I arrived at the institute at 7:30 AM.
I started working.
First, I had some tedious things to be done. Then I started writing a paper. When writing a paper, I need to concentrate myself only on writing. I need to be in my own time and space.
It was a pity I had a class today to teach.
Although I have not finished the paper, I made a progress. I felt good.
I returned home. Katya grilled chicken and potatoes, which was tasty.
