Helpful hints

Attention, barn-raised metro passengers: here are two rules (there are, of course, more, but we'll save those for another day)--
(1) Take up only one seat. Both seats are not for you. And I'm not talking about people who can't help but take up more than one seat; I'm talking about people who do so voluntarily.
(2) "I'm getting off here" is not a polite way to ask someone to stand up so that you can, indeed, exit the train. "I'm getting off here" is information. What you need is a request, such as, "excuse me."
