i think it's important to distinguish, at this point, between the two types of "intreaders".
one type looks away when you meet their (his) (her) (his/her) (hser) (heris) eyes, trying to pretend they were just passing from the advertisement behind your head to the scene outside the window, and the other gives you a geniune, vague, cheapskate smile.

i'm in the second category.

in addition, i think people with newspapers on trains should hold them up instead of hiding half the article under a fold in their laps.
