Impulses

I'm not sure if people are always like this in the real world but in the book, it seems like all the love-sick characters are intensely impulsive and almost never think about what they're going to say or do before hand. They are constantly hurting and misunderstanding each other, only to beg forgiveness later (and if they aren't forgiven, they wreak havoc with their plans of revenge). An example of such a case is when Heathcliff visits Catherine one time when Edgar is at church and she begs him for forgiveness. He says he can forgive her for causing him pain but he can't forgive her for causing herself pain. Another similar case that takes place between siblings is when Isabella marries Heathcliff without Edgar's approval and she later continually begs him to forgive her even though he seems resolute against doing so.
