However, everyone should do some form of martial arts, just to instill discipline in their lives, to the point where they can step away from bullshit encounters and then if, push comes to shove and you need to defend yourself, or someone else, you have the ability to drop them without hurting them too much.
Another tip: hope that somebody else than Fizzle is around who can do nothing more than to create a post on the internet giving advise to people who do not care instead of helping.
