Yeah, I was actually wondering this regarding the original letter from the person seated next to the obese passenger. Did you at least have the armrest down....which would help contain some of the incursion into your seat territory....or was it up? That’s a nightmare scenario; if it’s up and the person is already in…

Having been the fat person on a regional jet folding herself into plus size origami and nearly in tears worrying about encroaching on someone elses’ space: don’t be rude . You will survive . That “fat” person is probably twice as miserable as you are.

And, OMG these people, if you are part of a couple and you book an aisle seat and a window seat in the hopes that no one takes the middle and then someone sits in the middle seat and you don’t offer to switch and instead hold whole conversations over middle’s head YOU ARE MONSTER PEOPLE.
