VerboseThis is actually quite true. If I really know a person and that they really know me, then I tend to talk a lot. I can engage in utter useless conversation or an intense discussion for hours.
Lately my problem is that I haven't found anyone who I can be myself around. It's just better when the person knows all about you and they tell you to your face that they know. When that happens I let my guard down because I know I don't need to tell my life story and what they know is what they get, Plus it just makes me feel more interested in getting to know them and let them talk about themselves while I listen and jump into a proper conversation from time to time.
So if anyone knows me that well, I'll probably be a better friend and would feel more relaxed and calm.
