I want to throw a glass of water at my friend's face
Why do you want to throw a glass of water at your friend's face?
I'm upset with his behavior.
Throwing a glass of water into your friend's face is wrong. If you're upset with your friend, talk to them, don't just throw something in their face. That's not the way to resolve your disagreement.
Ok but I'm not sure if he'll listen but it's worth a try.
You're absolutely right. Instead of throwing things at your friend's face it's better to have a conversation with them.
