To recline or not reclince - that is the question. Do you recline on an airplane when someone is sitting behind you?

Yes, it's my seat

No, come on folks, space is limited enough

Well, I don't travel, but suppose I would

Well, if I do, don't end up hitting my seat because I reclined

No, dusch, if you do then yes, I will end up hitting your sit - if you travel more, you'd know not to recline and if you do, I will hit your seat - duesch.
