So why do they do it? This is only guys i have observed mind you but ive seen it in three of them. They can be snarky and will call you ugly and stuff like that. It actually annoys me greatly because i personally never ever ever pay out anyone. Yet they are supposedly stronger in than i am? Plus, they cannot take it in return. If you give them shit back they really take it to heart? I think part of the problem is my own strong Fi means that it annoys me when someone does this where other types might just see it as funny.
I personally see it as a sign of insecurity and unhealthiness but perhaps there is some other explanation?
