What if a woman hits me?

Let me start with some context.

I have just recently turned 20, and I am not one to get involved in gender wars. I just have my opinions, and I make do with them without being overly open about them. I'm male, if that has to do with anything.

I take the bus to and from college, and I have seen my fair share of women being rude to senior citizens and men in general. I've seen lesser men be that way to senior citizens and conductors. (Just what I've seen, can't speak for others). Before somebody mentions groping and molestation, yes, I know that happens to women a lot on buses and public transport in general, and I sympathize with victims.

Let's stay on rudeness. If a situation like that were to happen with me, and a random woman resorted to physical violence against me (a woman of any age), what would be the best response in your opinion? What would you do if any such thing happened to you (boys and girls are allowed to answer, am really curious about different perspectives).

Caveat: Let us say that the cause was totally unjustified for physical violence.

This post is not meant to spark controversy and debate. Just your perspectives are enough. Please, no fleeting generalizations.
