You were walking, late at night, then you saw someone beating someone else up, in a alleyway, you looked closer, and you saw a woman, beating up a man. You started to approach her slightly, but then she turned towards you, she was very muscular, and she was hoping to beat you up next. You didn't run, and she was amused by that. She walked right up to you, then said.

"Hello there~"

What do you do?
