how different is the last lecture neway?

Very different! So are the last set of exams. And ridiculous as it may seem, you are sure you will miss both. But that's probably true for most irksome things in life. They don't seem all that bad once you are done with them.
I am a stickler for keeping track of all firsts and lasts. So I battled a very adamant thursday afternoon nap and scurried through the heat (OT, its blazing hot these days!) into an air-conditioned Microprocessors class/lab. And since I've never been the type to keep nostalgic feelings to myself, I put the thought into everybody's head. And imagine my surprise when most people reacted the exact same way that I did with an "aaw...its the last lecture". We never wanted them to happen. We never wanted them to end. And thats the beauty of it.
