This is a gripe about the person who asks you to change your seat for an inferior one so that they can sit beside someone who they know. Then then they don’t talk to them at all throughout the flight. By which time you’re stuck somewhere inaccessible and can’t do a thing about it. For some reason it’s always the seat you’ve moved to that has the moron sitting in the row in front who reclines the seat fully back into your space. You can see the seat that you gave up and it is splendid in its isolation, free from reclinee interference. That’s when you realise you’ve been had. Next time you vow to say no to the request. But somehow you know that it would be churlish and you’ll be branded a misery.
