My hot chocolate !!

After almost a month I was back to class today. Not a very good time to be in class. It was from 3.15 to 5.30 pm. The thought of sitting in class for 2 long hours was by itself scary. I was in library from morning 10 going through some research papers and chatting with friends online. I dint have my lunch as well , called one of my friend for coffee but even he turned down the invite. I slept for some time and then grabbed a cup of hot chocolate. It was chill and cloudy and hence hot chocolate was like the apt thing for that moment. I entered the class and occupied a seat. In five minutes around 7 students were accumulated in the class. When the clock was showing 3.15 Professor Ubhaya entered. The course was Algorithm Analysis. This professor is very thin and I was very curious to know how he teaches like most of them in the class. Introduction to the subject went on well. I was having nice time as I had the company of my hot chocolate along with time and space complexity. I could feel the chocolate entering my throat, passing through my food pipe and landing in my stomach. Every sip of the chocolate was felt and enjoyed and so was the lecture. Every bit of what professor was explaining was easily grasped by my brain and enjoyed. Things went on very smooth until 4.30 and then I started feeling uneasy in the class. I felt my professor was not prepared for the class. After 4.30 whatever he spoke was not making much sense for me. I felt he was randomly speaking and it was more like he was speaking in a pseudo language. Just few minutes prior to that he had told something about pseudo code as well. He had to leave at 5 as he had some work. I strongly felt that after 4.30 even he was not happy in the class, he was also thinking about the place where he had to go after 5.
I was very disturbed after 4.30 and the reason was I had gulped my hot chocolate and I found my cup empty. This was the main reason for my restlessness and the coincidence was professor had brought a tumbler of water when he entered the class. Even that was empty at 4.30: p after 4.30 everything went off track because my hot chocolate, his tumbler of water and the topics for which he was prepared everything came to an end !!
