They may think of you like you think of them.
suggest taking a book and read which will take out the boredom of travelling or listening to songs or best, relax and go to sleep till you feel like. trains are the best places to relax, particularly if you are on upper berth. just relax and enjoy and dont bother about co-passengers. All kinds of persons travel in the train. its a matter of hours co-existence with them. once your destination is reached all will go on their own ways and may never meet again. dont have presumptions about anybody. Those you think are not smart may be much helpful to you in need of hour. thanks and thnk positively.
