Thanks to everyone who responded to my question. I think it's probably a combination of her believing that she's right about all the things she has said to me and being unaware of how this has affected me. Sometimes it feels like she just doesn't care, but obviously she does care about the little things.
I also think that it probably is easier for a lot of people to apologize for little things than for big things because they know that they will be easily forgiven. I suppose that trying to get forgiveness for big things is a much more daunting task, so some people decide that it isn't worth the effort. And maybe they are afraid that if they apologize for something truly hurtful, the person will just respond with more anger, because that is how they themselves would respond. I have been thinking a lot about this.
But in the case of my sister, I think she just really isn't sorry. It sometimes seems like she doesn't care, but maybe she's just oblivious to the hurt she has caused.
Thanks again for responding.
