If one is older than thirteen there's no reason to 'fight'. One might disagree with SO but throwing temper tantrums is not an efficient way of communicating and if this is the way of solving every day problems then maybe one's got bigger problem than that. Especially fighting in front of kids is suppose to teach them how to fight in adult life? For kids it's confusing and scary. And who's the winner? One with better argument or the one not crying?
