I am considerate of others at all times.

Standing to one side on an escalator is a tiny piece of civic arithmetic performed by people who will never meet. So is moving your bag off the seat before anyone has to ask, and finishing your call before you reach the counter.

None of it earns thanks and none of it is meant to. Consideration is mostly the practice of imagining someone who is not there yet - the next person through the door, whoever uses the kitchen after you. Whole cities run on this, and it holds together only because it goes uncounted.
