And I suggest you to eavesdrop on passengers’ conversations. If someone sits in front of you and gives a call to his friend and says he will get off at the next station, you should keep standing in front of him to take that a seat! If the sitting person complains to his friend that he will should go for a long time by subway, then move to another other sections to look for other seats. So don’t miss noteworthy information that surrounding people provide with you. Next, how do you sleep when you’re tired on the in subway? Though you have a seat, if you swing your head from left to right, and as a result, you  may lean your head on the a person sitting next to you, then he or she is sure to take your head off his or her shoulder. So it’ll be the best to take a seat on the edge of the window side. You can lean your head back on the edge of the window so that you can have a good sleep without shaking your head. Only be careful not to open your mouth or drool in your sleep. Hope you maintain your gentle image during your subway trip.
