Suppose that someone of whom one is not fond walks up to you while you are having a conversation with another and stands quite too close for comfort and you ask them to get out of your personal space. Instead of doing so, they stand even closer to you before sarcastically asking "oh, how's this?" While standing up taller than before to deliberately, threateningly, lean into your face more than before. The individual's entire intention is to violate your personal space against your declared wishes so as to humiliate you.
If you hit this person, would you be arrested?
