I'm going to swear and threaten the life of my boyfriend's coworker after I told her not to touch my hair. She did anyways
Is there any kind of prior conflict between you and that coworker?
Not really. She just keeps touching my hair.
She should respect your personal space. Having said that, you shouldn't threaten people either.
I think I'll be fine if I don't do anything violent. I just want to yell at her nonchalantly when I see her.
It is ok to tell her how you feel, however violence is not the answer. Maybe she will understand where you are coming from and decide to stop touching your hair since it bothers you.
