Some short people just don't get it
At 6'7 I can attest to you that most definitely you reclining your seat ruins my day. Depending on the plane the odds were already stacked against me getting my meal tray down, now you've guaranteed it will stop on my splayed legs on either side of your reclined seat and sit at a 45 degree angle in the air.
Those same metal hinges hurt like a b*tch when you slam back.
If I ask you nicely to leave your seat upright after you've tried ramming it through my knees 5 times enjoy having your seat kicked/kneed at my every opportunity.
