I am one of those people who tends to be a bit more considerate of those behind me, whether in F or Y. I rarely recline on a shorter flight and when I do, its only slightly.
On a flight from DFW to ORD yesterday in F and the short person in front of me, flung her seat back and slammed my laptop screen onto my hands. Just goes to show that just because you fly in the front, does not mean you have class.
