Courtesy Tips for Riding the T

There's been an increasing lack of courtesy in Boston lately, and most of it happens on the T.
Here are some of the unwritten (until now) rules of common courtesy:

1. If you have a backpack or a large shoulder bag, please place it on the floor between your feet. It will create more space on the T, and you will also avoid hitting shorter people or seated people in the face.

2. Please do not yell "excuse me" and push past the people who are also trying to get on/off the T. I do not wish to be pushed down the stairs.

3. Please move all the way into the car. You will have time to get off the train at your stop.

4. Please give up your seat to a temporary or permanent disabled person, a pregnant woman, an elderly person, or anyone that you think could use it more than you.

5. If you must insist on sitting on the outer seat of a double seat, at least please offer to let someone in to the empty inner seat. Please do not set your bags on the other seat, preventing anyone from sitting there.

6. Please do not put your wet umbrellas on the seat.

7. Please let people off the train before you board. Once we are off, you will have room to get on.

Feel free to add any that I may have forgotten!
