Since there's not much to gain from friends fighting, I'd try to be the peacemaker <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />. I wouldn't side, I'd just tell them not to be so childish, drop your pride and make frinds again.
But as Stone sais, why they fight IS improtant.
Allso note that I've never been in this situation. I think that this is what I would try to do, but I can't be sure. It's like figuring if you will panic or stay calm if you're in a car on the bottom of the ocean, and you've only got one hour of air. You've never been in a situation like that, so you can't really say what you will do.
