Washington Post columnist Gene Weingarten knows that flying is uncomfortable enough (strict carry-on rules, awkward TSA patdowns) without a rude invasion of space by your fellow passengers. Cramped quarters on most airplanes make it downright inhumane to recline your seat, minimizing the already-meager leg room of the person behind you.

In an effort to avoid such problems, Weingarten created a printable card for travelers that asks the occupants of the seats in front of them to refrain from reclining.

He says his invention is a “small, righteously indignant way we can battle the airlines while retaining our humanity.” Now, if we could only get a card that urges babies to stop crying at 30,000 feet.
