Over the years, I've watched a ton of movies where two best friends argue over a man or a job or a wedding venue and proceed to get into a huge, hair-pulling, fist o'cuffs fight. After rolling around on the ground and being stopped just short of knocking out teeth, the two rise and become sworn enemies or even BETTER friends. I say that this scenario is a bunch of bologna and real life just doesn't work this way.
Moreover, I've rarely seen feuding friends get physical over a problem...heck, they may not even get verbal. What happens is a "falling out". Friend A betrays a secret or some other violation of the friend code. Friend B finds out and proceeds to freeze out Friend A. The phone calls, invitations, and outings cease. Friend A wonders what is going on. Feelings are hurt. One day, they see each other out with different people. They both politely say that they need to get together sometime soon. And they don't.
I've seen men get mad and get over it. They're back to being best buds by the next day. Go ahead- I know you're calling me sexist. It's not true, but I won't be mad.
