Violence might not be the best choice of resolving issues, but there are times when you get punched against the wall so badly you're left with no choice but to push back.
I have to confess, I've been in a physical brawl once, okay, maybe two or more times in the past. Well, they all happened when I was much younger. You know how kids always wants to show who's stronger or tougher. Those were the kinds of situations that pulled me into a physical confrontations which ended in a fight.
Sometimes when I think back, I realize how stupid I was. Most of those fights were over silly things that we'll end up laughing over it when we talk about it now.
Violence isn't the key to any situation. It in fact worsens the situation and likely to give rise to revenge brawls at any given opportunity. The best line of action during any heated confrontation is to simply just walk away regardless of the situation.
