Believes and Science....

Everyone was busy doing their own thing at the office. I was doing the same until I felt a little bored. Then, I stood up and walk over to look for Kelly, one of the administrative gals in the office. I checked her room, she wasn't there. Disappointed. I checked the other room. Right when I stick ma head in the room, I heard a thunder-like bang. I thought to myself, something heavy must had hit the ground really hard. Quickly, I look down in search of that thing. To my surprise, one of the office gals who was looking for something fell down from her chair. I didn't go and help her up because she stood up faster then I could get to her. So, I paced back to my own little corner to continue my job.
After a few while, in chaotic mode, another office gal stormed into my side of the office and starting yelling for help from me. Without hesitating, I ran over to aid her and at the corner of my eye, the gal who fell on the ground was roaming around in the side of the office frantically searching for something. When asked what was she looking for, she repeatedly replied "Have you seen my thing?" I was puzzled at her answer. A minute later, the other two office gals stepped into the office and witnessed the event. They asked the same question I was asking to the gal who felt down the chair. To no prevail, she replied the same. We couldn't do anything to help comfort her down. Soon, another office guy walked into the scene. She quickly packed her things, grabbed an umbrella, her cell phone, and hand bag, then left the office like she was running away from a frightful lion.
She left the office. The office became silence and heavy. Everyone was trying to absorb what was going on, perhaps busy formulating and analyzing the rather random and crazy event. The silence was broken by our boss as he walked in intentionally was looking for someone. We then rehearse the event to him and these are the answer we were given to him.

One of us said she has problem.
One of us said she was stressed by something.
One of us said she got possesed by some dark dirty evil spirit and that she has the same "history" at her previous companies.
and I said she might be suffering from a severe degree of depression.

So, what are you thinking right now? Is this a disturbing incident that imposes you to think that one can analyze an incident in many different point of view?
