" Edgar, there's a difference between missing him and wanting nothing to change," she said. "They aren't the same things at all. And we can't do anything about either one. Things always change. Things would be changing right now if your father were alive, Edgar. That's just life. You can fight it or you accept it. The only difference is, if you accept it, you can get to do other things. If you fight it, you're stuck in the same spot forever. Does that make sense?"
But aren't some changes worth fighting?"
You know that's true."
So how do you know which is which?"
I don't know a way to tell for sure," she said. "You ask, 'Why am I really fighting this?' If the answer is 'Because I'm scared of what things will be like,' then, most times, you're fighting for the wrong reason."
And if that's not the answer?"
Then you dig in your heels and you fight and fight and fight. But you have to be absolutely sure you can handle a different kind of change, because in the end, things will change anyway, just not that way. In fact, if you get into a fight like that, it pretty much guarantees things are going to change. "
