I'm so tired today. I got three classes since morning (7.30 AM) and i got another one at 1.30 PM and the last class was on 4.30 PM. During the break, i read an email which stated that i had to have 7 class meetings before the mid test, so i was forced to combine two chapters of the book into one class meeting.
At night, after i finished teaching the last class, i had a talk with some of my students and we had a chat for some time. I got home around 8.30. So tired today, but it's now over. Time to get some sleep.
