Professor is no show!!

After a tough morning of getting the booth removed of my car the time to go to class was getting closer and closer. Although it was 10 minutes before class, I decided to go to class early, this was the first time I was gonna show up to class early! As I looked towards the teacher's desk, to my surprise, he hadn't arrived yet, I was shocked to notice this because I always thought the teacher would arrive before anyone from this class. Since this was my first time arriving early, I looked around to see how many were also here early, and there was only 5 other people, 2 of them which had their laptops open. As soon as I sat down, I turned to see what the two guys with the laptops open were doing, to my surprise, one of them was playing "slither.io", which he seemed to be doing really good on that game, judging based on the size of the worm, and the other one was playing some game that involved tanks.
As the time for class start time was getting closer, more and more people were arriving, by the time it was 10:30, almost all students were here, except the professor. After a few minutes of sitting in silence, my friend arrived a little bit of late, and as he stared at the professors desk, he stated, "wow, and I thought I was late", after nobody responded he went to sit down at his usual seat. After a few minutes since my friend sat down, he got impatient and said out loud, "did he even sent an email", referring to the teacher, as everyone looked through their phones, finally someone responded and said, "no, he didn't". As soon as 15 minutes had passed since the time class was supposed to start, my friend got really impatient, and said, "you know what I'm gonna leave". As left many people got up and left along, as time was passing by more and more people were starting to leave, until only me and 4 other people were left.
After looking through my Facebook for a few minutes, I finally got tired and left.
