I pretended someone had something on their forehead and I hinted to them to wipe it off as a joke.
What made you do that to someone?
Because I fucking hated her, she's such a bitch and I don't like her social status.
Even when you don't like somebody, you shouldn't do something like pretend they have something there to make them look. It will make you look like a bully.
I'll do it anyway and see what happens.
If you don't like her just leave her alone and avoid her. Being mean and playing tricks on her will only make things worse.
