Bonus in Life!

Started to prepare at 9.00 pm for next morning's exam!! Just studied all night and morning too.. Kept reading the book.. Seemed like the chapters would never end. Was reading even when the
prof entered the room.Just the time when papers started to be distributed,I thought of getting over and keeping rest to the luck.. but then there came the best surprise.. Prof says to keep the books open!! The exam was made Open book!!!yipeeee.. It was a real "peace".
So is this what is called bonus in life!?
