I mean, I asked the question, and then I followed through to SEE. It was the results that weren't pretty.
It's not actually about being intimidating or anything, I don't think -- I honestly think it's about habits and patterns of behavior. Those who can be very social, outgoing, and tend to be confident -- the majority of the time, they're driving relationships, since they have the energy / push to do so.
It creates a pattern of behavior:
I always say good morning to my friend. If I stop saying good morning, the friend is not going to intuit it's because I want THEM to, they're going to assume I don't want to talk, or they did something, or -- any number of things, none of which are "hey, maybe it's my turn to pick up reins I have literally never held". Because I changed the terms of our relationship without including them in the discussion about it.
