Well, I've been guilty of standing in the rear galley and talking with the flight attendants & others during an international flight, or a long domestic.
I do have a problem with leg-jumps when I sit for a long period of time. If I get up periodically I can keep the effects at a minimum.
Usually I only chat in the galley area, unless there's a bathroom line. If I'm in that line, I do admit to chatting with others in the line.

On the flip side, I had a business class seat (paid for with ff miles) and it was right in front of the lavatory, and had to put up with the door being slammed shut all night long. Since my reclined seat bumped up to the rear wall, I could feel the ripple over and over and over all night long.

I guess my point is that an airplane isn't exactly a hotel room, so you have to live with the conflicting needs/behavior of other passengers.

Much as I HATED the slamming door.

PS, and I promise to be more aware of people sitting in seats when I'm in the aisle and not talk loudly if it's "sleeping" time.
