You misunderstand, ashleyn. They don't recline to sleep - they recline for "comfort". By which I mean they recline to reduce the comfort of the person behind, who is obviously inferiior and has no need to watch a movie or read a book or try to work.
I recline to sleep - that is the only justifiable reason to do so IMHO, but the world is full of "reclining disputes" it seems.
I get it Moody, believe me. That is why I fly J or choose exit row. Problem solved.
