On airplanes: do not recline your seat.
Even if you’re tired.
Even if the person in front of you has reclined theirs.
Even if the person behind you is eating a tunafish sandwich.
Of course it’s allowed (the reclining and the inconsiderate eating).
But that doesn’t mean it's good.
Your wins don't count for more than their losses.
From upright seat 11E: sending you love and wishes for good future things.
