I'm going to swat at a woman for grabbing my necklace
Do you want the woman to apologize?
No, I just want to scare her, for teasing me.
Instead of taking a swipe at her, communicate to her what she did was wrong. Trying to hit her will not make your message land properly.
I am so angry, I'd rather hit her.
She should not have tried to take your necklace, but retaliating back physically is not right either. Tell her that she should not touch things that are not hers.
