this thought came up when we friends were writing exams...we were really tired and had sleepless nights.
So,just like that out of the blue, we wished for sleeping buses.that is,we wanted to sleep while going home,n be woken up by alarms set to a particular bus-stop that would be there for every passenger in the form of earphones hanging from the front seat.Then, I can sleep peacefully,until my stop comes.I think just like fb,n other such things...even this would become a reality in future :)
