since this is Wasteland, I'm putting my 2 cents forth.
It amazes me that in all my years on God's earth, I've realized one thing that is very distinct between men & women.
When women argue or even look at each other cross eyed, you can guarantee pretty much that they're going to be arch rivals for life (or for at least a very long time, lol).
When blokes have a disagreement, they can punch each others lights out but within 24 hrs be sharing a beer together.
PS: there are exceptions on occasion (ie Steve & Craig) but I'm almost certain they are from the Hermaphrodite variety J/K boys
