No classes!

Today, I woke up around 6.30 when the sky started to lit up. Lately I have been waking up earlier than the time I set my alarm to ring. As I had an hour to spare before the alarm started to ring, I decided to fall back to sleep but it wasn't very useful because I ended up sleeping but waking up from time to time tossing around the bed.
At last, I decided to wake up around 10 minutes before the alarm rang and started to browse my daily web pages before having my breakfast.
After leaving the house, while waiting at the bus stop near my house, I received a call from my fellow classmate who called to tell me that the university was being secured and evacuated. Not knowing what was going on, I asked her to try using the backdoor and call back later.
During that time, I was all hyped up and told my housemates whom were waiting with me at the bus stop about the news while thinking of the idea that we might not have classes.
Not long after, my friend in the university called back saying that both entrances were secured and the building was being evacuated. We told her to stay where she is and to meet us at the university front door.
Upon reaching there, we saw policemen and fire brigades stationed in front of the university and securing the university only allowing exit and forbiding anyone from entering the area.
After looking around for people we know, we finally got a few versions of what was happening:
1. This was a fire drill (Though I think it was highly impossible as the drill we had last time was in the evening, when all classes were about to end, while this time it was around an hour after classes had started. And every1 were too confused about what was going on while the last time everyone knew that it was a fire drill)
2. Someone crazy called the school saying that there was a bomb planted in the area.
I personally think that the second reason was more likely as everyone did not know what was going on and heard several people saying that there was a bomb in a school.
Anyway, I am glad that classes were cancelled as the subject that we were having today wasn't really very important.
