Sitting, Waiting, Wishing

Just sitting at my seat, still in office, waiting for the damn test case to run, wishing nothing goes wrong.
The whole atmosphere of office changes when everyone's left (well, almost)
Some people are still sitting, creating craters on the cushion beneath them.
All in all, there seem to the following categories of people who stay till wee hours of the day (or night) in the office -

• The guy, who has been given work, much more than he can handle.
• The guy, who is eager to complete the job of 2 days in 1 day. Maybe he wants to impress his boss or maybe is too ambitious (or disillusioned, I may say :))
• The guy, who wasted all day, giving company to everyone going for a smoke, coffee.
• The latecomer. He probably reached office after enjoying a leisurely brunch and deserves to stay late for completing those mandatory 8.25hrs/day.
  

Which category do I fit in?
Don't know. Don't have enough time to think about that.

Damn! the test case failed.
