Are you saying that the person sitting behind has more right to be comfortable than the person in the front?
How is reclining in your seat being inconsiderate?
You are just trying to get comfortable when you are packed in like sardines. Both people should be comfortable, not one or the other.
It's more inconsiderate/selfish to force someone else to be uncomfortable so that you can be comfortable. Reasonable people should compromise and not act like jackasses.
Another reason that I rarely fly... Only when I have to.
