Should I call this woman ugly in front of everyone?
That seems mean. Do you think it will be an effective way of telling her?
No, but I want to do it.
You shouldn't say mean things to people. Everyone else will think you're a weirdo if you blurt something out like that.
I want to do it because I can. I know it will make her cry if do.
It will make her cry, anybody would if somebody said something mean to them. You don't have to like her but you shouldn't be mean to her and call her out like that because she is different.
