As an anecdotal personal example. I love my wife and kids dearly. I trust them, and feel no anxiety being around them. Yet it’s draining. Now they’re gone for a few days, and I feel very good being finally alone for a few days.
Likewise I enjoy getting together with friends and family. I’ve also learned to be sociable. But it’s draining. After a day of having to interact with people I really, really, really cherish being alone for a few hours with my own thoughts, and preferably silence.
We’re different like that, people in general, I mean.
