Ony in IDC will you find people hanging around the department making fun and ofcourse doing work at late nights. And it could be as late as 1:00 to 3:00 pm at night. It is a usual scenario here.
And ever wondered what would it be like having classes after dinner and all of you arrive without dinner at the classes. It goes for an hour and all of you including your teachers feel hungry and then we have a dinner bash. All of us dine together and get back to work.
That's what allures the working here and excites.
