Hi-tech Surprise!

Late afternoon in office today, no work in hand, I lazily got up to grab a cup of coffee. Walking down the aisle just couple of cubicles away I heard that screeching sound again. 5-10 seconds and it was gone. It was the sound I had heard many a times from that cubicle and I knew the person also, but never asked her about the sound. I had just crossed the cubicle and just missed seeing what it was.

To describe in brief about the lady in the cube : quite a sportive person, short and smart looking with long straight hair; very good at interacting with people; keeps visiting different countries often; innovative and brilliant at her work. I have become a secret fan of hers!
I had assumed it might be her hobby to collect toy cars - sports cars, she kept one in her desk drawers and at times she played with it, rubs the wheels against her hands and rotates the wheels, which causes that screeching sound. I also assumed at what point of time she might be doing that - like she just figured a solution (says Eureka! in her mind) and plays with the car!!! or before a meeting (c'on its time to go!!) plays once with it and off!!
Amazing how mind imagines and creates its own picture - just out of one screeching sound!!

Today I decided to cross-verify, if my assumption of source of sound was correct, so stepped back few cubicles and asked her - hey I was wondering for quite sometime now, what was that sound you just made? She started laughing and then she replied Its my pencil-sharpener!!!! And she brought it out to show it to me and started explaining how it worked and why she was not quite happy with it etc. I was dumbfounded for a moment and then laughed out aloud! Its a hi-tech sharpener, insert the pencil in the sharper, a small motor inside automatically starts and rotates inside (making the sound!!!) to sharpen the pencil!
'Gotta meeting, cya later' she said and off she went. She had sharpened the pencil for the meeting!
