It was my Birthday.
But I welcomed this day at work. So it was around 0:30am when I left office.
Slept a bit at home.
Came back to work at 8:00am.
And... I couldn't leave office while it was still the 27th. I left at 1:00am from office. (Interesting that about 7 people were still working when I left)
Just work today. Nothing more.

I have to be careful of my health.
