Haha. I guess it depends on the argument. If it's something small, then it'll usually start off a bit heated before ending in laughter with us poking fun at each other.
If it's a BIG argument, then the situation is very different. Typical ESFJ, I HATE confrontation, where as my partner will confidently take on literally anyone for an argument (which weirdly is one of things I massively admire about him when it's being used for a good cause). When this situation does happen it will normally result in me clamming up, which unfortunately makes him even more heated because he thinks I'm just giving him the 'silent treatment' when I'm actually not. Rational goes out the window on both sides. We'll normally just go to different parts of the house until we've both calmed down, and then afterwards we'll talk about it all rationally. Given we've been together 13 years at the end of this month, this way of dealing with a 'big argument' must be working well for us if/and when one does happen haha.
