Me either. It's really given me something to think about. I have spat apologies back in people's faces in the past, because they refused to use the word sorry. For me, knowing that they care about my mental state is far more valuable to me than understanding why they did what they did. I don't really care why they did it in fact. I was always taught that "I'm sorry" is what you say when you're apologising and "I apologise" is what you say when you're not actually sorry, but wish to move past the barrier created by the incident. But then again, I guess it's like all language. The important part is the idea communicated, not the sounds used to do so.
