THEORY OF THE SHATTERED GLASS

This is an interesting incident that happened a few days back.

I entered the office as usual humming to my own tunes, lost in my own world and then i suddenly stop. Nice design!!! Wen did he get this done, maybe last evening.( My bosses cabin has a glass window, which was apparently broken. But the design was so pretty, it was uniformly distributed from top to bottom) Then i realized "OMG!! It's broken." All the nuerons in my brain started working and finally by i came up with these conclusions:
1. First possible reason was -someone was playing cricket in the corridor and the ball hit the glass. ( ppl in my team love playin cricket esp in the corridor)
2. The maintainence guys broke it. Some big instrument hit the window and it cracked.
3. There was a difference in temperture inside the room and outside the room and the glass cracked under the influence of the difference in temperature. (here i shud tell u that wen the glass broke it had an epicenter on the top left corner of the glass and the glass had cracked evenly from top to bottom, forming a design similar to one seen wen a car's windshield cars but covering the whole glass window). Now, my theory was that this epicenter was the weakest point in the window, i.e. at this point there was a bubble or the glass sturcture was uneven here. Since, it was the weakest point, it cracked first due to the difference in temp. and since, the glass has been designed such that it doesnt crumble wen it is broken at a single point, it got shattered all over.
4. This is my fav one- My bosses angry vibes were inside the room and they just wanted to come out, there was no other way, so the glass broke and his angry vibes were free...
5. This ones creepy- There was a soul trapped inside the room which wanted to come out. It found the weakest point and came out of the room, only to haunt the rest of the floor!!!

My boss didn't agree with the 3rd one, even though our discussion went on for half an hour, then finally i gave in... after all he's my boss. And dont worry i never told him abt the 4th and the 5th one, and it wud be good for me if he doesnt get to kno abt those also..;)
