I'm going to pour out water on someone smoking downstairs.
Why would you do that to a smoker?
I hate smoke and I want to get rid of it from my house. I hate smokers.
Although the smoker is in the wrong for doing that, you should not spill water on people. You should tell the person to leave.
I'm doing it in a minute.
Please don't this is not the way to handle issues, use your words and the outcome will be much better.
