He refused to listen to me and so I'm thinking of throwing pieces of bread.
Don't you think he will be upset?
I want to hurt his soul inside him
While it is understandable to be upset that somebody is not listening to you, you shouldn't throw things. People are not obligated to listen to you and it is wrong for you to want to force it.
It's fine. I'm learning how to develop people skills on how to deal with this stuff.
Well then you need to learn that you don't always need to listen to people, but throwing bread is considered very rude. How about you just ignore him and don't throw anything?
