At the school or in the office, do you have the habit of playing pen?  

Until now I still don't know how to play that trick wherein the pen seems to be rotating all over your hands/fingertips.I'm amazed with my classmates who were doing that.I've tried and practiced many times but until now I still can't get the trick.So I envy you for knowing the trick.Just set you limit because it might annoy your officemates.

No, I don't have that habit. First, I can't make the pen on my fignertips turn a circle; Second, my fingers are always busy typing on the keyboard, only when I need to sign the documents I use the pen.

in school time, this is one thing we must do at brake or in classes. some of those guys in my classroom even rotate books or schoolbags very well. they can keep for quite a long time, without stopping. at that time, we even compare who was doing the best? and it was quite cool if you can do very well, especially if you can play books or schoolbags. now in the office, this is not so offten as before, but there was once, on a meeting and i was playing a pen unconsciously and then suddenly the boss ask " do you learn this from your school?"
