I'm not sad about my best friend's uncle dying
Are you sad about how your friend feels?
Yes, I'm sad for my friend
At least you feel bad for your friend. It is hard to feel bad if you did not know the guy.
I don't feel bad. He was my best friend's uncle and he was mean to her.
Well I am saying that you feel bad that your friend is upset. It makes sense for you to not be upset since you did not really know the guy.
