Invigilation duty

Two days ago, due to some sudden problem, Ramanathan Sir gave me duty of invigilating, actuarial students, for 2 hours (some internal assessment). I thought waste of two hours, and will be bored. But I took some problem with me for solving.
But it was entirely opposite. It was fun doing that. All the time I was wondering and remembering my days, when I used to be on that side. When they used to look here and there then it reminded me how I also did that so often. I had a strong dislike for filling sheets over sheets, which most of the friends used to do; so my answer sheet used to be have least possible number of pages (one reason was I used to study least so nothing to write :P). And consequently, I was always in habit of running away from Examination hall, even if I had things to write, as I was very lazy. And if in case someone tries to gets up before me, it was like a challenge to me; and then I can't allow another one to do that.
It always appeared to my mind, to tell the teacher, please take viva, but don't ask me to write. Aur agar nahi araha to why to keep pondering over the question paper until the last minute. Is some angel about to appear all of a sudden and tell me what is the answer to that question?..
(Back to present...) Alas, many of the students did the same. Kept staring on the paper and window alternatively. And for a change on there class fellows too. I have no idea about the difficulty level of paper. Couldn't make out a single question (except for the last question which asked about some Taylor's law, in which I knew the word Taylor, atleast :()
I thought of making some sketch, but it was more interesting to sit idle and watch them.
