The Brotherhood exists, whether you want to believe it or not. We Brothers roam the world like sleepless zombies, we meet each other all the time. I've sat behind, next to and infornt Brothers before but we never spoke of it. We all silently acknowledged our common belonging. A Brother, if he has the Window seat, will always place his bag and his jacket in the overhead compartment before he asks you to get up. A Grand Master Brother would also get out his Laptop and Book and take them with him to his Window seat. Not only this, a Brother sitting in the Window seat will also acknowledge that he has no right to accessing the overhead compartment during the whole flight, unless you (the Aisle Brother) is in the bathroom.
It's easy to spot a Brother sitting infornt of you, for this Brother will never move the back of his seat, even after the "Fasten your Seat belt"sign has been turned off. It's because he knows that the 2 inches the back of his seat moves will not magically turn his seat into a bed. More importantly he realizes that those 2 inches are the only remaining two inches for you (the Brother sitting behind) to breath.
This is but only a fraction of what we do, for we belong to the Brotherhood of the Economy-class Flyers: BEF.
