When people say they are sorry for my situation (whatever that may be). What do they have to be sorry about? Did they intend for something negative to happen to me? I know people genuinely mean well but it is such a weird (and I find it fairly patronising) thing to write.
I'm also a bit annoyed that I read what people write rather than what they mean, but that's a story for another day.
I think you are confusing "sorry I caused that" with "sorry you are suffering".
I can be sorry for your situation because I care about you (or people in general), without having played any part in the cause of your suffering.
Nope, not confused at all.
