a lot has to do with environment, things can sometimes change from r to k depending on situation of environment. r and k often mix, it usually isn't mutual tho, k wants monogamy and to slowly rais a kid to be another k where r just wants to bang and make babies. r does not care about the raising of the offspring like k does. a lot has to do with how you were raised too. if you are raised by a k family chances are you will strive for the same. r grows up in single familyhomes where momma is popin out babies with mutipule people in a life time so r does not have the ability to become a k even if it wants to, all r knows is r behavior. r will strive to get k because they want the stability but the second another k comes around r is swept to the side because k knows r is not able to stay monogamous and that is not what k is looking for. its kind of like the intro to idiocracy. 8D the stupid breed offten while the smart take their time.
