You know school has started when-
1) your eye bags resurface
2) you start whining and complaining incessantly to anyone who would lend a listening ear
3) your heart starts palpitating from the physical exhaustion
4) you begin to zone out more frequently
5) you suffer from headaches as a result of the brain drain
6) you receive emails/smses from random project group mates
7) you start reading notes on the train/bus
8) you try to keep awake by listening to more pop/hip-hop/rock music
9) you sigh more
10 work keeps piling up
11) and you turn in a few minutes, and then a few hours later than your original bed-time.
