I feel like there are basically three "tiers" that you move through in your relationship with people. Like the first is when you meet and you're typically pleasant and talk about agreeable things like the weather or how you met, or the people you met through, etc. The second is where you get to know them better and find out about their habits, their peeves, likes and dislikes, and you start having Actual Discussions where you can kind of start to disagree or discuss certain things that you wouldn't at the beginning. The third stage is where you're close and you feel comfortable teasing them or arguing with them and knowing they'll take it the right way and won't be automatically offended, because you've sort of laid a foundation for it.
I was at a work party and we were all at Tier I with each other. I still don't know some names. My coworker, however, (the one I've complained about before, thinking she knows better than everyone else/is right all the time) went straight for arguing about literally everything anyone mentioned. From the weather ("No, it isn't going to rain.") to clothing ("That trend must just be in this country, I never see it elsewhere") to food ("Don't you think it's fine sitting out? It'll still be cold enough when we eat.") and it just killed the conversation. But it wasn't that she just disagreed/was argumentative about everything, she never offered ways to continue the conversation. Just jumped in, said her sentence, and sat back while we all stared at each other and tried to find a new topic.
