I was just sitting behind you, minding my own business, trying to watch a poorly-formatted TV show on a screen with duller colours than my first cell phone, enjoying my wine from a plastic cup when, out of nowhere, high up on the so-called friendly skies, bam, the back of your head, the screen, the wine, the tray table ... all a lot closer to my face. Now I can't see the screen properly, the tray table is trying to cut through my stomach, and you're only 10 per cent more horizontal than you were before, so we're all losers here.
It's a matter of common courtesy. Just because you have the option to recline, it does not mean that you should. You can, of course, there is no law to stop you doing so. But why would you do that to the person behind you? Why would you invade their personal space like that, especially as their personal space is already so small?
You don't even have to be a tall person to be uncomfortable on a plane. If you have legs, with knees, you're not likely to have a good time on a long-haul flight. The last thing you need is someone reversing the back of their seat all the way up to your nose just so they can be under the illusion that they're lying down (they're not even remotely lying down, they're just being rude and not even for that great a gain for themselves).
The one thing that unites us all inside that plane is the fact that we all paid a whole heap of money to be incredible uncomfortable for a long period of time. That could be a strong bond but you're ruining any possibility of us ever getting along by acting selfishly. If you recline your seat, you're making a bad situation even worse for someone else. That makes you an asshole.
To the person who sat in front of me on the flight back to Auckland yesterday morning: I'll never see your face - although I'm all too familiar with the back of your head - but you, sir, are a selfish moron.
