Maybe this is just me – but I doubt it. In theory, everything should either be reasonable or unreasonable, right? However, certain things exist in my mind some place between those black and white choices.
For example, it seems reasonable for your bride to ask you to take out the trash, it does not feel unreasonable not to do it, and it feels unreasonable if she comments on you not doing it. Or, it does not seem reasonable to expect her to have sex when she is dead tired, but you still find yourself upset she is unwilling.
My guess is these grey areas show us places where our reason and our desires are in conflict. We know better, but our selfishness colours how we look at things.
