Ha, I wish. The level of comfort with someone really only effects the rate of energy drain, at least in my case.

But that's not what I'm saying - I'm saying conversation drains me even if I'm with someone I'm comfortable with. I'm tired when it's over. My wife is not. She comes home excited.

It's very much like I have a hidden meter for dealing with other people. Once it's full, I'm done with people. It doesn't really matter how much I like or trust these people. I can get burned out from talking to folks at work and need space from my family and vice-versa. I just need time to be alone and not have to consider making conversation or entertaining anyone. I need space for my thoughts to expand and to not be constantly distracted by other people's "noise". I love my wife. I love my kids. I enjoy spending time with them. But when that social meter is full, regardless of how it got full, I have little ability to engage with them.

> Im pretty sure everybody gets energized once they've gotten fully comfortable with someone.

They don't though. You just sound like an extrovert that can't fathom that introverts exist.

Even if my family visit me and I am comfortable with them, I will still be extremely tired when they leave. I won't feel "energised"
